Title: 1976 GMC Motorhome
Post by: SONIC. on Mar 16, 2016, 18:21:38
In case anyone is interested in this I don't see the harm in throwing up a build thread here.

It's been going for about 6 months so it will just be old updates for now until I catch up.

We'll start from the beginning.

The GMC motorhome is the only motorhome ever manufactured by a major car company.
In the 70's it was the creme of the crop, 455 cubic inch beast of a motor from a Toronado, independent adjustable rear air suspension, luxury interiors, the whole package. Beast mode.

Fast forward about 40 years and now they are mostly dilapidated or kept running by a very devoted and passionate group of (old) folks.
I have yet to see any one besides mine that has the kind of attention to detail and modern design that I am going for.

As I brought her home:
4500 bucks, in decent shape other than the paint.
(http://i67.photobucket.com/albums/h298/jbrady2/GMC/1_zpszojtv4qe.png) (http://s67.photobucket.com/user/jbrady2/media/GMC/1_zpszojtv4qe.png.html)

The original plan was to gut the interior and do her up nicely. That all changed, but we will start there anyway.
Did a sketchup of the basic design.
(http://i67.photobucket.com/albums/h298/jbrady2/GMC/3_zpsdcnyec8c.png) (http://s67.photobucket.com/user/jbrady2/media/GMC/3_zpsdcnyec8c.png.html)

First thing I did was focus on the dash. I wanted to keep the retro feel to it but make it modern to fit the new interior.
So we recovered the old crazy 70's green pleather stuff with marine vinyl:
(http://i67.photobucket.com/albums/h298/jbrady2/GMC/IMG_6009_zpswddqeaub.jpg) (http://s67.photobucket.com/user/jbrady2/media/GMC/IMG_6009_zpswddqeaub.jpg.html)
(http://i67.photobucket.com/albums/h298/jbrady2/GMC/BBF403C1-A64A-4305-AD86-CDC7825D5DFA_zpsx4b7ipzt.jpg) (http://s67.photobucket.com/user/jbrady2/media/GMC/BBF403C1-A64A-4305-AD86-CDC7825D5DFA_zpsx4b7ipzt.jpg.html)
Also painted the funky green plastic with a white epoxy paint:
(http://i67.photobucket.com/albums/h298/jbrady2/GMC/IMG_6020_zpsxohoe2ts.jpg) (http://s67.photobucket.com/user/jbrady2/media/GMC/IMG_6020_zpsxohoe2ts.jpg.html)
(http://i67.photobucket.com/albums/h298/jbrady2/GMC/IMG_6019_zpsb8friclq.jpg) (http://s67.photobucket.com/user/jbrady2/media/GMC/IMG_6019_zpsb8friclq.jpg.html)
Then added some walnut accents to the dash vents:
(http://i67.photobucket.com/albums/h298/jbrady2/GMC/6474B0C1-1CA4-47C7-93D2-72D1A8A7D177_zpsfgwf5qua.jpg) (http://s67.photobucket.com/user/jbrady2/media/GMC/6474B0C1-1CA4-47C7-93D2-72D1A8A7D177_zpsfgwf5qua.jpg.html)
(http://i67.photobucket.com/albums/h298/jbrady2/GMC/0A47A30E-1512-44FF-A9B5-B1CF5F8C5940_zpstn2a3mpc.jpg) (http://s67.photobucket.com/user/jbrady2/media/GMC/0A47A30E-1512-44FF-A9B5-B1CF5F8C5940_zpstn2a3mpc.jpg.html)

From there I decided to really step the dash up and made a completely new dash panel from walnut and inlaid a tablet in it. The tablet is connected to a wideband 02 sensor for AFR, a vacuum gauge, a transmission and oil temp gauge, as well as controlling all the stereo stuff and gps etc.
Mockup:

And finished product:

Installment 2:
After getting the dash mostly done I tackled the door panels.
Whoever designed this thing did a great job except for one thing. NO Fucking cupholders. Are you serious?
So I had to redo the door panels to have a cup holder, I didn't want to go through the trouble of fiberglassing:
(http://i67.photobucket.com/albums/h298/jbrady2/GMC/B5AE4EB2-05EA-48BF-8D60-22ED4E192CF0_zpspllj0bg8.jpg) (http://s67.photobucket.com/user/jbrady2/media/GMC/B5AE4EB2-05EA-48BF-8D60-22ED4E192CF0_zpspllj0bg8.jpg.html)

Beautiful.
These will be covered in the same grey as the dash at some point. Took them to an upholstry shop to have them done after I failed miserably, and after 3 months the guy went out of business and I had to go repeatedly stand at his door until he showed up to get them back as they aren't replaceable. He said "sorry man i just couldn't do them for what I quoted you" "THEN CALL ME AND TELL ME THAT YOU ASSHOLE"

Onward

I am happy to see that you're actually going through with the Reno. Keep up the good work, man.

After that, I took a break from the dash to do some mechanicals.

The GMC has air ride suspension in the rear. 2 air bags are inflated and deflated individually to control the tilt and height of the rear end.
In stock form it has a tiny tank and a tiny compressor that takes forever to fill the bags to change the level. That wasn't going to cut it becuase well who wants tiny things?
So I yanked all that shit out and built my own compressor setup with a viair 444C and a 2.5 gallon tank. This will allow me to air up tires, tubes, balloons whatever the hell I want, along with run air tools on the side of the road if the need arises. Also it's cool.
(http://i67.photobucket.com/albums/h298/jbrady2/GMC/D9A17E60-5FC3-4213-B9E2-571450FB0DCE_zpshrzthdtm.jpg) (http://s67.photobucket.com/user/jbrady2/media/GMC/D9A17E60-5FC3-4213-B9E2-571450FB0DCE_zpshrzthdtm.jpg.html)
(http://i67.photobucket.com/albums/h298/jbrady2/GMC/2F6062A0-2991-4DCC-A624-D270C9FB18D7_zpsey9azgvn.jpg) (http://s67.photobucket.com/user/jbrady2/media/GMC/2F6062A0-2991-4DCC-A624-D270C9FB18D7_zpsey9azgvn.jpg.html)

The tank runs to a bunch of solenoids that allow me to air up and down from the dash, as well as to sending units for the air pressure gauge in the dash.


Getting it mounted was a bit tricky. The original compressor system is housed in the back in an interior cabinet. It's loud and obnoxious and takes up valuable interior space. So I put this one in front of the passender drive wheel, with soem rearranging of the start battery and a radiator hose, it worked out perfectly.
(http://i67.photobucket.com/albums/h298/jbrady2/GMC/4720BCAD-AEA7-4008-9B66-74C490BD9C89_zpsuwgulv0p.jpg) (http://s67.photobucket.com/user/jbrady2/media/GMC/4720BCAD-AEA7-4008-9B66-74C490BD9C89_zpsuwgulv0p.jpg.html)
Here's the pressure gauge
(http://i67.photobucket.com/albums/h298/jbrady2/GMC/4B5637A8-B2D3-4499-91F6-F53E98B3E765_zpsqpuj5pj0.jpg) (http://s67.photobucket.com/user/jbrady2/media/GMC/4B5637A8-B2D3-4499-91F6-F53E98B3E765_zpsqpuj5pj0.jpg.html)
I wanted one with dual needles so I could read both bags at once, as well as with remote pressure sensors so I didn't have to add leak prone plumbing into the cab. It's no fun driving down the road when one air bag looses pressure as you can imagine.

Once that was done and plumbed I started playing with the engine a bit.
When I drove it 3 hours home it wasn't wanting to shift very well. Had to really coax it into 3rd.
Ended up being really simple after a lot of searching, the vacuum modulator was hooked to the wrong vacuum port bu the idiot PO. Once I corrected that it shifted like a dream. And believe it or not this thing is awesome to drive.

Power steering and brakes, cruise control, air ride suspension, quiet as a mouse. It's really mindblowing that this came out of the 70's.

Next up was power. I had read that these things were crazy powerful. Mine would haul me down the road but I certainly wouldn't call it crazy powerful. I almost chocked it up to the fact that all of these are owned by people who would think a prius is "crazy powerful" but i started investigating anyway.
Pulled the engine cover and pushed the pedal to the floor and watched the quadrajet do it's thing. Or not do it's thing. Secondaries never opened. WTF.
Turns out the throttle linkage to the pedal was bent, meaning that when the pedal was on the floor the butterfly was only halfway open.

FUCKING A RIGHT
A test drive later and a bunch of grins and some new burnout marks on the road and she's a whole different animal. Cruises at 75 with no problem. 455 Cubic Inches of Big Block greatness.

Everyone that has one reports about 10mpg, which is actually really good for a motorhome. Thanks to GMC for actually designing a vehicle and not a house on the back of a truck!

Joostan, 10mpg ain't bad at all outta that engine/chassis. Did you do any other tuning to it? Ignition/wires/etc?

And Eric, you should do some tuning as well. I get 15mpg outta my Stepside ;)

  My old man claims mine never got more than 10mpg since it came off the lot in 1979.  He says that knowing he took the 305 out and put a 350 in.  LOL  If I can ever make it to Spring Break, the truck is getting a valve job, some other bits and the Holley dyno tuned.  I'd be very happy at 15mpg.  The Ram averages between 12 and 14mpg.  How I drive should also be considered in this conversation.

Once the interior is done and the paint is done (biiiig money on paint unfortunately) I'm going to go with the new FiTech fuel injection system.
Mostly for reliability and altitude immunity but there should be a bit of a performance bump as well.
Knowing me once it's done I'll get bored again and do headers, exhaust,cam etc

I considered putting a aftermarket FI kit on the Stepside for much the same reasons. Consistency and Tune-ability. But since she really only sees weekend duty these days, it's hard to justify the expense.

Oh, and btw... I have a pair of Big Block C10 longtube headers in the shed. Yours when you're ready ;) :P

I've been following these for years.  Congratulations, I'm envious.  Three or four years ago I saw one of these for sale down the road from Mid-Ohio.  It looked to be in very excellent, non-restored condition... have regretted not following up on it ever since.

Looks like you've gotten a really good start w/ it.  I know that two of the big problems w/ these over the years has been the air suspension system and rusted frame rails.  Looks like you did a great job with the air system.  If the frame rails don't need attention you will be in great shape, everything else should just be tinkering, imagination, and time/money.  I guess it isn't impossible to replace most of the window glass but I have heard the windshields are practically made of "unobtanium."  I've seen these around at wildly differing prices; from very inexpensive for units that are not much more than "for parts" to really top dollar for ones that have been, part by part, brought into 21st century technology.  I'll bet that w/ FI, headers, electronic ignition, and other attention you ought to be able to get near the gas mileage you would like to see.  I heard once that somebody was working on a kit to adapt a modern pickup diesel to that transaxle, but when I went to research it later I couldn't find any more info.

There is a similar, but smaller, unit that was made by Winnebago called the Lesharo a few years back.  It wasn't as big as the GMC but had similar functionality.  That one mostly suffered from a crappy French Renault 4-cyl power plant that wasn't up to the task and didn't hold up well.  There was a company (Dakotas or Montana?) that did a complete conversion to the GM 3.8L drivetrain and even used most of the dash components.  I guess the real ticket for that one was to find a donor from the supercharged 3.8L Buick.

Nice to see someone is familiar with them!

Prices are all over the board, the die hard guys have a few guys who do "official" appraisals for insurance companies, and decent shape coaches with minimal updates are "appraised" at 30-40K which is complete crap, but it helpw with insurance. You've got a bunch of guys out there who because of this think they have gold sitting in their yard when in reality it will take 20+K to get it back to decent shape.
The GMC guys always say you can spend 15K on a decent coach that doesnt need much work, or you can buy a  junker and spend 15K getting it where you want it. This is a fair assessment if you do your own work. At 80-100 an hour if you farm it out things get pricey really really fast.

If anyone is interested in how fast prices add up on a project this size I am keeping up with every penny spent on this project. If you had shown me this before I bought it I probably would have turned and run the other way. I honestly thought I was going to finish it for under 10 total! Granted I have gone way over what i initially wanted to do, basically every piece of this thing except the engine and body will be new. Also, I am cheap as shit so every part on this list is one hell of a deal or I wouldn't have bought it.
A fucking RV REFRIGERATOR is 1000 + dollars. What the fuck.
https://docs.google.com/spreadsheets/d/1oS7dyvqXN5YiLDre7IoalMo_Q2viMw_YMOkxQc6G8nc/edit#gid=0

The suspension and the frame rails are the problem (everything else is aluminum or SMC)
I went and saw one before I found this one that had bad frame rails, instant no go. This one just has surface rust no pitting or problem areas.
There are a few guys who are just die hard devoted to these things, and almost all parts are available, but they are way pricey since the demand is so low, windshields are 6-800 each (need 2)

There's a guy who just finished his first road trip with a duramax engined coach, tons and tons of work went into that. He ended up with 13mpg over the 1000 mile trip. not bad, but for the 10+K and years of labor involved can't say I'm too interested!

Yup,
I decided from the very beginning to do this right the first time, if it costs more so be it, it may just take longer to complete.
So that means a 120V/Propane fride. So nice to not have to use electricity when out int he middle of nowhere and not have to run the 6500 watt generator to keep the beers cold.

I ended up getting a fridge on CL brand new in the box "damaged" for 189 bucks. the Damage was a scratch on a part I'm going to paint anyway.

Where was I?
From there I started with the tear down again.
The floors were a little worse for wear (probably fine, but there was a hump that was going to fuck up my nice floors)
So of course they had to go.
(http://i67.photobucket.com/albums/h298/jbrady2/GMC/A24D30BC-C8CB-40FE-8373-00F411DC8DA9_zpsogots8mw.jpg) (http://s67.photobucket.com/user/jbrady2/media/GMC/A24D30BC-C8CB-40FE-8373-00F411DC8DA9_zpsogots8mw.jpg.html)
Luckily pulling the entire floor made running all new fuel lines and air lines quite easy.

I also found that 9 of the factory 15 body mounts were either crushed or gone, so I made some new ones to fix that issue.
Jacks are for people with time to pump them up, so I grabbed the forklift to do the body mounts:

After that was done we put in all new floors. with much better insulation underneath to minimize road noise and help keep cool/warm

From there I spent a ton of time with a sawzall removing all the 40 yr old insulation. This was a HUGE bitch, and will never be repeated. If I do this again, I will simply spray over the old foam with new to fill in the shitty factory job. Way more work than it's worth.

The GMC came stock with a 6500 watt Onan Generator. Not running when I got it.
I changed the starter bracket, new points and condenser (see this is starting to sound more familiar right?) pulled and cleaned the heads and valves and Whalla! a 40 YR old genset purring and making power. A little loud, and a gas guzzler but who cares.
This was a while back when everything was still together actually.
One day we had it running the AC's and all of the sudden the pitch changed the lights went out and I smelled smoke.
The governor had gone out, putting 200+ Volts into the 120 system and frying the brand new converter. FUCK.

At this point I said fuck that and started looking for a honda.
I found a EV6010 6000W liquid cooled genset from another GMC guy and that gets us back to present.

Yanked the Onan (made it into a backup generator for the house).
Made a new mounting tray for the Honda using the CNC:

The old AC units began to bug me. They are a bit loud the amp draw is a bit higher than I wanted (20) and I hated the way they looked up there.
So I got 2 Coleman Mach8 low profile ones to replace them. Got a hell of a deal on them.
They are longer and thinner than the stock ones so I had to mount the rear one backwards, but it shouldn't matter as it won't be run when we are moving anyway.

During my time in the Air Force I was stationed in Germany for five years.  During that time I was able to come back to the States a couple of times on AF space available flights, usually on a big C-5A.  On those planes the passenger compartment is way up at the top behind the wing root and the cargo area is just a big, ol' cave.  On one trip back the only thing in the cargo area was one of these GMC motorhomes that the Loadmaster told me had been used as a field office during exercises by some Army general.  Wonder if it really was an Urban Assault Vehicle?   ;D  8)

So after the AC's were sorted it was time to work on the inside a bit.

Got the generator casing installed and covered in dynamat like material to help kill the noise of the generator and reflect the heat.

For the propane compartment I decided early to ditch the built in tank in favor of 2 20lb grill cylinders. I lose a little capacity, but I can fill them anywhere or just trade them out at any gas station. A LOT more convenient than trying to find a LP dealer or RV dealer in an unfamiliar place. This presented some problems because the propane compartment wasnt quite big enough to hold both tanks AND the batteries. So i tossed the old one and built a new one. It required beinding some plywood to get the back to sit against the body, but no big deal otherwise. Now I have ample space for 2 LP tanks, 4 batteries, and some other goodies.

The stock compartment basically stopped at the back of the door, so the new one gives me an additional foot and a half or so to put the second tank in the left side of the compartment.

The next major hurdle was wiring this thing.
It's a little more complicated than a bike.

I've got 3 different power sources, Generator (120) Shore Power (plugged in 120) and Battery power (12V).
The 120V feeds a converter, which converts 120 AC to 12 DC.
The Battery Feeds an Inverter that converts 12 DC to 120AC.
And I wanted the shore and generator to switch automatically so I don't have to go flipping breakers to switch from one to another.

A problem a lot of people face is if the inverter is connected to the same circuits as everything else then when it's running your converter is also running unless you turn it off. This means you are using battery power to charge your batteries. Not a good plan.
So I started with that. I put it on a separate circuit that is connected to a transfer switch. If plugged in to shore power or the generator is on the switch bypasses the inverter and powers directly from the 120, saving the batteries. If the shore power and generator arent in use, the switch switches to the inverter to power the things I want powered by 120 when not plugged in (stereo, TV, and a couple of outlets). Pretty slick.

The generator and the shore power are both connected to an auto switching transfer switch, so power comes from whichever is putting out power (the transfer switch is  just a few high power relays).

Diagram below:
(http://i67.photobucket.com/albums/h298/jbrady2/GMC/power%20diagram_zpsdwnwxswx.png) (http://s67.photobucket.com/user/jbrady2/media/GMC/power%20diagram_zpsdwnwxswx.png.html)

To make all this work I had to modify the breaker box to have 3 separate parts, so I cut the connectors and epoxied it back in place, easy.

Here's what it looks like put together without any wiring
(http://i67.photobucket.com/albums/h298/jbrady2/GMC/IMG_20151228_173413581_zpsygd3xqrx.jpg) (http://s67.photobucket.com/user/jbrady2/media/GMC/IMG_20151228_173413581_zpsygd3xqrx.jpg.html)

Next was wiring and plumbing.
I decided to go with a tankless water heater, because I like long showers, when not hooked up I can take short ones, but when hooked to shore water with the tankless heater I can take as long as I damn well please!

For the wiring I so far have used 500 ft of 14ga primary wire, 50 ft of 4 AWG welding wire, and 100 FT of 6 AWG welding wire.
The primary wire runs all the DC circuits, mostly for the LED Lights and the vent fans.
The 4AWG fruns from the battery bank to the inverter, the generator, and the DC distribution panel/converter.
The 6AWG runs from the battery bank to the solar charger, to the engine battery and eventually to the solar panels, I haven't gotten that far yet though.

This is what that fucking mess looks like:
(http://i67.photobucket.com/albums/h298/jbrady2/GMC/IMG_20160306_115510695_zpsfylhxwvl.jpg) (http://s67.photobucket.com/user/jbrady2/media/GMC/IMG_20160306_115510695_zpsfylhxwvl.jpg.html)

The spray foam will cover most of it up.

And besides a lot of little stuff that I won't bore you with, that's pretty much where we sit at present.
I hope to cut an opening for a vent fan in the bathroom, and hopefully get some foam sprayed this weekend.

How thick are the wires on the shore cable? What kind of circuit protection do they have?

Electric tankless water heaters (for home use) generally pull well over 100A. They often require three 8AWG hookups spread across three 40A breakers.

Are you adding the 12v to 120v inverter?  The reason I'm asking is that most RVs I've seen usually go the other way; 120v to 12v.  This keeps your house battery charged when you are plugged in and most of the interior lighting is usually 12v so they work when you're on the road or dry camping.  While on the road the engine charges both the chassis battery and the house battery but the chassis battery is isolated from the house circuits so using your house 12v power doesn't run down the chassis battery and leave you stranded.  I noticed you said earlier that you will be using 4 batteries.  I'm assuming these are all house batteries, are you going to use four six volt batteries for your house battery set-up?

Do you live in a climate where you are going to have to winterize it so your pipes don't freeze in the winter?  If so you are going to have to add in a 3-valve isolation piping system around your water heater so you can isolate it when you run the antifreeze into the lines.  You don't want to put that stuff into the heater.  It gets isolated and then just drained.

The inverter is so that I can run the TV and stereo and use an outlet while I am out in the middle of nowhere without running the generator. It is added on, not that any of this is stock haha.

The house batts will also be wired to the alternator as you described.
Yes the house batts are 6v deep cycle wired in series for 12v.

The plan is to not use antifreeze, I'll use compressed air to blow out the lines for winterizing.

Understood, sounds good.  In my trailer the TV is 120v so if we were dry camping TV is a no go... wouldn't bother me, but the Mrs would revolt!  My van had a 13" analog TV and a VCR, both of which were pretty much useless, like new, but useless.  It's got a shore cable, house battery, and the whole set up, but I was able to find a 19" digital TV w/ DVD (less than $100) that uses 12v as its primary power so it was an easy switch-out for the original.  In my searching I found several TVs and stereo units that were 12v.

It is funny how close offgrid sheds and motorhomes are to each other.

12v led lighting will save on a heap of power as well. And the few at the shed are bloody bright.

My van and trailer have been converted to 100% LED lighting on the 12v circuits, both the house and chassis (except the headlights on the van).  I've used several different kinds depending on the application, but found an eBay vendor (autosaver88) who has great prices and ships really fast from the US west coast.  We've been really happy w/ the results.

Since you guys mentioned it haha.
The lighting in this one will be all LED, with a warm white color temp as opposed to the classic LED blue.
I couldn't find any that I particularly liked in the states for the price I wanted to pay, so I placed an order straight from china for 200 of them  8)
I kept 30 and sold the rest to other gmcer's. They are pretty sweet, 4 watts each and the light color is great.

With the battery power I am going to have and the ridiculously low draw of the LED's (.2 amps apiece when I tested) I should be able to leave the lights on for several days straight and still have battery leftover. Coupled with the solor and the generator I shouldn't ever have a problem with power  8)

And yep Brodie, this one is basically meant to be a mobile off grid hideaway/weekend warriormobile.
I got it so that I could toss some bikes on the back and drive 4 or 5 hours on a friday night, spend all day sat and sunday playing and then drive back sunday night, all for a few bucks of gas.
As cool as it sounds to strap everything to the ADV bike and go camping, it's really not feasable (or pleasant) with a significant other on the back.

A little more progress made lately.
I got the black tank repaired and installed a few days ago.
Got the last of the 12V wiring done in the battery compartment.
Went with a lot of marine stuff intended for boats.
Got a Morningstar 25A solar controller, a Blue Sea ACR (combiner), a battery cutoff switch and a distribution block to clean up the wiring.
(http://i67.photobucket.com/albums/h298/jbrady2/GMC/IMG_20160323_180019520_zpstvtsoskd.jpg) (http://s67.photobucket.com/user/jbrady2/media/GMC/IMG_20160323_180019520_zpstvtsoskd.jpg.html)
From the distribution block the 4 wires run to: Generator, inverter, converter/DC panel, and input from solar.

We are going to start with 215ah of battery (2 6v duracell gc2's) and see where that takes us. I have room for 2 more in the propane/battery compartment and could also fit 2 more int eh generator compartment if needed.

Once the batteries were in I had to weld an extension to the exhaust for the EV6010
(http://i67.photobucket.com/albums/h298/jbrady2/GMC/IMG_20160322_171916397_zps8depooll.jpg) (http://s67.photobucket.com/user/jbrady2/media/GMC/IMG_20160322_171916397_zps8depooll.jpg.html)

Got it installed and she cranked right up after I lowered the rear of the coach (pretty low on fuel at the moment). It's pretty loud inside the coach, but there's no insulation or anything yet so I'm hopeful that it will tone down once it's all finished up. I'l definitely be adding insulation to the gen compartment to try and tone it down a bit. I still need to extend the exhaust out from below the coach past the rear bumper.

Next up is insulation. So as soon as I get a free day I'll be experimenting with this spray foam stuff and will report back with how it works.

I looked at those for my basement, it would end up costing me 2x as much as hiring it out but in your situation it should be cheaper. I think for less than 500 Sq feet the DYI kits are better, after that the pros get the foam cheaper and cost less.

Exactly.
Got a 600bdft kit that will hopefully cover it.

Title: Re: 1976 GMC Motorhome
Post by: SONIC. on Mar 31, 2016, 10:00:06
Yeah,
I cant quite figure out how they manage to get away with the prices. I paid 582 dollars for a kit that would not even insulate a room in a home.
It's not like its overly complex or expensive to make, the biggest expense is the tanks it comes in, and I'll admit that they aren't cheap.
But from a commercial standpoint, you're buying chemicals in a 55 gallon drum and the spray setup is minimal.
Seems to me they would get more business and make more money if they just lowered the prices to be a bit more competitive with traditional insulation.

I guess in the end it's like anything else, charge as much as you can get away with, especially when you have the superior product.

Must be the market, I can get foam done here in my basement, which I hope to do this fall for just a little more than I can buy the bats and do it the old fashion way, big benefit to foam is no vapor barrier needed and it fills nooks and crannies better etc. But I wouldn't be using it if it was priced higher.
\
also in your case Justin the foam will add some rigidity to the RV walls and can be sprayed and stuck to the doors and stuff around your compartments to sound proof as well as insulate.

Exactly. A friend built a new home with pro installed foam and the off gassing made his kids very sick, headaches, nose bleeds. He spent 10's of thousands having the foam removed and still couldn't live in it. Ended up selling at a huge loss. I can't imagine how bad it could be in a sealed motor home.

Exactly, that's the big advantage and the main reason I am going with the foam in this instance. The walls are 1/8" aluminum, so the foam will adhere and add a lot of rigidity, making for less road noise, less movement of joints etc.

Post by: Maritime on Mar 31, 2016, 11:07:53
And as for off gassing, it really depends on the type of foam, all foam off gases for a period of time, some of it for a few hours, some for a few days, some for years so you need to research the product being applied so it is the right one for your application. The stuff the contractor here uses is done off gassing 100% in 24 hours, guaranteed and its right in the MSDS for it.  I am sensitive to odors and I went and saw a job they had done 2 days before and there was 0 odor, they also run a huge ventilator while spraying basements to keep the gases out of the rest of the house.

In Iraq the Army used spray foam, about 3 to 4 inches thick, on the outside of tents and temporary large tent - like buildings. Prior to the foam the temp inside would reach 105 in the summer, with AC. After it was at a cool 85. The space was much quieter and felt more "solid."

XV thats way cool the stuff is super effective.

I got it all sprayed in yesterday, it wasn't too bad. got a really good coating everywhere, way way better than the factory insulation (which was a joke)
(http://i67.photobucket.com/albums/h298/jbrady2/GMC/IMG_20160402_122237980_zpshxvuyqja.jpg) (http://s67.photobucket.com/user/jbrady2/media/GMC/IMG_20160402_122237980_zpshxvuyqja.jpg.html)

Took about 5 hours including taping and trimming. The 600bdft kit was more than enough, got a really good coating on the generator compartment.

Bit milestone here, means we can finally move on to the interior.

So it's been a minute here!
We've been slowly chipping away at this.
We just got the ceiling in and the LED's installed last night.
(http://www.thegmcrv.com/wp-content/uploads/2016/05/wp-1462930654005-1080x608.jpg)
(http://www.thegmcrv.com/wp-content/uploads/2016/05/wp-1462930622694-768x432.jpg)

Pretty awesome.
Copy paste from blog:
One of the things that I was most disappointed in the stock GMC was the lighting. Something about it just felt off. From the weird rectangle things under the upper cabinets to the undercabinets that reminded me of an emergency exit path on a plane, I just didn’t dig it. Add that to the lack of decent overhead lighting and we’ve got a recipe for a change!
So what to do? Very early on in this process I started looking for lighting. I knew what I wanted It was just hard to find. When I finally came across it it was pricey, but perfect. While searching on Amazon I found 4W LED Panel Lights, the size was right (4.5″ wide, 1/2″ thick and flush mount) and they looked awesome. At 10 bucks a piece they weren’t cheap, but not too high either so I ordered a few.


The lights came in and the look, fit and feel was great! But the color was off. The ones I found had a 6500 Kelvin color temperature (which in laymen terms means they are that horrific surgical blue that all the assholes in civics put in their headlights to feel cool). At this point I contacted some of my sources in the Peoples Republic of China and found out who the best manufacturer of LED’s over there is. I contacted them and sure enough they make the amazon lights. We chatted a bit and I told them I wanted 3000 Kelvin color temp and they agreed and made up some samples and sent them over.

What a difference! 3000K in my opinion is perfect, they feel just right. Nice warm white-ish yellow light very similar to what you’re used to from an incandescent.
So I placed an order, minimum quantity put me in the LED business and we’ve been selling them ever since to many happy customers. (They are available in the store)
After getting our ceiling up (that will be a different post when it’s finished) We tackled the lighting install which is a very simple task with these LED’s.
They come with a 5.5mm x 2.1mm male plug as seen in the photo above. You can either cut this off and wire as you normally would (red to + black to -) or you can use an adapter to make them removable (also in the picture). We went with adapters because, well you never know. If one bites the dust its a simple 1 minute job to replace it this way. If using the screw on terminals the best way I have found is to strip your wires about 3/16 of an inch and twist the strands together. Unscrew the screw and push the wire into the appropriate slot (labeled) and screw it down tight. I recommend putting heat shrink over the whole shebang once you’re finished for a nice clean install.
We used a hole saw (3 5/8″) to drill the holes for the lights. Our wiring was run before we did the spray foam so it’s just hanging from the ceiling. Pop the lights in the holes and whalla! Let there be light. During the day time we were not sure how it was going to work out, they didn’t look very bright so we thought maybe we would need to add more. When we came out after dark we were very pleasantly  surprised! We have 8 lights installed (2 more to go in the bathroom when the walls are up) and the brightness is perfect. Not so bright to run you out, but plenty bright to work or make dinner or just relax. We are so pleased with the outcome!

Now on to the really awesome part!
I hooked up the Victron Battery Monitor to see how we were doing on amp draw. One of the biggest upsides to converting to LED is the tiny power requirement for the amount of light coming out. We have a total of 8 lights on when these photos were taken.

So the whole coach is lit up like an airport and we’re pulling a whopping 1.82 amps. That’s .2275 amps per light. Realistically we will never have more than 4 on at a time so our normal amp draw will be .91 amps or 11.5 Watts, or in laymens terms, nearly nothing.

For comparison the standard 1156 automotive bulb that your GMC has now is 21 watts…..each…….so this whole lighting system draws the same as if you have one of the tiny little lights on in your coach.
According to the battery monitor (which hasn’t been calibrated yet so I’m sure it’s wrong) we will get 90 hours of light at full blast before we drain the batteries to 50%. Not bad. Not bad at all.

Whoops..If that doesn't just make ya cringe.

Okay so where the hell was I?
No clue.

Anyway, we've made a bunch of progress on this thing. It's (like I think i already said?) a TON of work. Several thousand manhours in so far.
But yesterday we hit a real milestone. We finished the Building Phase.
All of the cabinets, bathroom, seating, bedroom etc is finished.
This bedroom was the finishing touch on the woodwork.


I have no good photos but here's a teaser I'll try to take some decent ones today.

Next up is finish work. Lots of it.

I really planned on taking photos of everything and doing a detailed log, but it would be 500 pages long with 15000 photos so I said fuckit and just put my head down and built stuff.

Plan is to be up and rolling by march for shakedown. We plan on driving it out to Grand Teton to get married this coming July, so we've got a solid deadline to stick to.

This is the "dinette". We don't like a traditional dinette booth thing so i came up with this, 95% of the time it will just be a big couch lounge thing and then the table lifts up if you want to eat at a table. I've since added a nice curved section to that big open hole in the back corner. The big hole in the front is now a big drawer that houses the beer cooler.
Lots of storage underneath as well as space for a bigass subwoofer :D

Beautiful work. The wine niche is a nice touch. Did you consider using a bendable plywood on the dinette corner radius (one that doesn't require kerf cuts)? I've never done a radius like that but I'd like to try it on some custom kitchen cabinets.

Thanks,
The wine was a last minute decision because the water valve was hige so the wall ended up being way too thick, so we needed to use the space
I considered it, but all it is is kerfed core, so the added expense was not something I cared to deal with when I have a CNC that will make the kerfs for me in a few minutes. I'll go back and fill the kerfs in the final finishing stage so you won't know they are there once they are veneered over. A little more work but saved me several trips to the lumber store.

Sonic, love the cabinets in the back of your coach, ironically I'm on the GMC Net...I was looking for the cockpit cup holder pictures and found you here too...what filler did you use, I'm mounting an aux evaporator below the window on both sides and will need to modify my side panels...would like to something like the cup holders too...I have a 73 Canyonlands...but also have been rebuilding a 65 Yamaha YDS3c scrambler.  Got my frame powder coated, most of the shiny bits ready, need someone to paint my tins (ying-yang style tank) although it's an early vin (complete with notched pistons) I want to make it a cafe, I can never leave anything alone, like my wife's 66 mustang with the tripower, 6 cyl.  Cool to see your handiwork...you should share it over at Gmcnet, despite all the old guys, there are a lot of new members migrating from fb...

More progress this weekend.
Got all the cabinets finished and the floor in.
Went with a product called Core-Tec, it looks great and it's 100% vinyl so no particle board backer meaning no(ok minimal) expansion and contraction.

The bed area got a wrap around headboard/footboard as well. The TV is mounted to a linear actuator behind the footboard and raises and lowers with a switch which turned out really fucking cool.
I'll post up a video at some point.

Dude this thing is the nuts.  Me and the wife lived in an old VW camper van for a few summers in Ibiza, thought it would be a good idea to sort out the body work and give it a re-spray while we were living in it. 

"Coupla sheets of sandpaper and two weeks and I'll have it looking good as new"  I said.

"Two weeks?"  she said.

"Two weeks.  Max."  I said.

"Ok, you got two weeks.  Don't fuck this up."  she said.  Firmly.

Well, I fucked it all up, took 7 weeks.  In 100 degree heat.  While living in it.  In hindsight it was a terrible idea, but man that thing looked sweet when I finished.  The things we do for camper vans man, worth every bit of blood, every tear and every ear splitting chew-out from the missus.

Kathleen was not keen on the showering shitter approach (i though it would be convenient, just take a dump, turn around for a second and step out...like a built in bidet! )

So we went with a dry bath, but the whole floor will be tile, so i decided to waterproof the whole floor just to be safe.
The seat over there will be walnut flowing down from the countertop and the toilet is on the left side of the picture of the floor.
The shower pan's going to be CNC machined from a big ass chunk of butcher block walnut.

There's a little more space there than it looks like in the pictures.

Not going to speak for what he did specifically, but there are urethane grouts to handle the job. 
Title: Re: 1976 GMC Motorhome
Post by: SONIC. on Feb 21, 2017, 11:46:14
Tim it's a multi step solution to the moving cracking problem.

Step 1 is the redcoat, if the grout cracks the water should not rot out the wood beneath, it hopefully will eventually find it's way to the drains.
Step 2 is an epoxy thinset that's flexible.
Step 3 is using Sonite (epoxy tiles) in a very small size (1/2" mosaic tiles, 1/16" thick) , so the tile themselves won't crack.
Step 4 As Eric said, urethane grout with extra flex additive to make the grout flexible enough to withstand the constant earthquake that is being mobile.

Step 5...hope for the best  8)

Oh and you can see it in the pictures, but all the corners got a fiberglass mesh membrane between layers of waterproofing to keep the corners solid with the flexing.

I did get the shower pan built.
I had to do it twice because the first one I forgot to offset the drain hole by 1/2". Whoops. Good thing I've got plenty of walnut sitting around haha.

Design in cad so the water all drains:

(http://www.thegmcrv.com/wp-content/uploads/2017/03/IMG_20170221_173703756-1336x1002.jpg)

Send through the widebelt to flatten it out, then a skim pass on the CNC to get it perfectly flat on the bottom. Flip it over and:

 (http://www.thegmcrv.com/wp-content/uploads/2017/03/IMG_20170311_142915720-1336x1002.jpg)

(http://www.thegmcrv.com/wp-content/uploads/2017/03/IMG_20170311_170550159-1336x1002.jpg)

(http://www.thegmcrv.com/wp-content/uploads/2017/03/IMG_20170311_183538301-1336x1002.jpg)

The clamps are by a company called JLT, worth every penny if you do a lot of gluing.
I made a few clamps using their design before I bought theirs, they aren't complicated, but I have 80 of them so I decided to just buy them instead of spend weeks making them. The clamps themselves run about $100-150 each depending on the length.

Hopefully you won't have to make a third pan, now that the drain lines up, but if you do your CNC could mill a grid of 3/4" x 1/8" or so convex dimples onto the surface with a small ball-nose.

Thanks dudes, I really need a better camera

Supergyro, weight on the pan is roughly 15lbs I would say.
Not really much heavier than the fiberglass one I based it on.

about 50lbs of sawdust was made from the central part of it!

Also all the countertops will be CNC'd on the bottom to give a sort of web design to keep the strength but cut out a lot of weight.
I honestly think that even after the tile and the wood countertops we'll be just as heavy as stock, since it was all made with dead heavy particle board everything. I used ultra light ply to offset the weight of the cool stuff

Got some time last night to get the tile set. Still need to grout, but have to wait 24 hours for the thinset to dry.

After staring at the wall for an hour trying to decide how the hell to cut the tile to fit the crazy shape we had an epiphany.
We cut the exact same wall out of the saved file on the CNC and laid it flat. BOOM easy peasy.

We used resin tile so the only way to cut it is with a band saw, which is a huge pain in the ass because they are so tiny and want to fly off everywhere if you don't do it just right. Anyway that all worked out just fine, took several hours but in the end totally worth it.
(http://www.thegmcrv.com/wp-content/uploads/2017/03/IMG_20170322_182311465-1002x1336.jpg)

Once we had that laid out we mixed up a bucket of Laticrete 254 Platium and went to town.
(http://www.thegmcrv.com/wp-content/uploads/2017/03/IMG_20170322_210158740-1002x1336.jpg)

It went pretty smoothly, a little running back and forth to the bandsaw to trim a few spots but ended up working well,
Probably took an hour to the do the big wall and then 45 minutes to do the rest.

And here we sit before grout.

The ugly grout lines in the corners are getting covered by walnut seating so we didn't bother to make them pretty.
There are 2 spots where the grout lines got a little big, but oh well nothing can be done now. You get into a bit of a fog while laying it haha

Thanks guys.

Been a little busy and not a lot of progress.
Over the last few days I finally completed the last piece of the dash puzzle.
The original AC controls looked awful, like they were out of a mid 70's gm pos hah.
So after a bit of searching I randomly bought the controls from a 2004 Ford Fusion and adapted them to work.
It has a mechanical blend door and vacuum controls.
I had to turn down and machine the original blend door lever to fit in the new housing, worked a treat. Then had to swap the cables to get the heat/cool function working the correct direction.
(http://www.thegmcrv.com/wp-content/uploads/2017/04/IMG_20170407_203943075-1336x1002.jpg)

Then I machined up a new walnut face plate, I'll laser engrave all the little symbols at a later date.
(http://www.thegmcrv.com/wp-content/uploads/2017/04/IMG_20170409_134218132-1336x1002.jpg)

Quite the difference:
(http://www.thegmcrv.com/wp-content/uploads/2017/04/IMG_20170410_180510094-1336x1002.jpg)

Next up in preparation for reinstalling the dash was a layer of sound deadening and heat killing heavy stuff. Looks like the space station in here now.

(http://www.thegmcrv.com/wp-content/uploads/2017/04/IMG_20170416_141237871-1336x1002.jpg)

had to spend all night last night redoing the actual dash panel because for some fucking reason the file went haywire from my old one, so I had to start from scratch.
5+ hours later:
(http://www.thegmcrv.com/wp-content/uploads/2017/04/IMG_20170418_223001796-1336x1002.jpg)

I've got a tablet in there for music and nav, backup camera, Etc. I can also see my battery charging status and details, along with details on the solar panels, all from the dash.

On the left is the controller for the fuel injection and timing. Pretty cool how adjustable it is, it also gives me coolant temp, air intake temp, vacuum, spark advance, AFR, and about 500 other things that I'd never need to know like throttle position etc.

Title: Re: 1976 GMC Motorhome
Post by: SONIC. on May 12, 2017, 10:09:41
Too much haha.
It's a funny story actually, I was searching everywhere to find a decent painter around here for a reasonable cost. I sold my 69 GMC truck to fund the paint.
One of the guys that came to look at the truck came down from Indianapolis. He didn't buy the truck but we got to talking and he owns a huge body shop and buys these old trucks to restore and flip. He has a paint booth big enough as well as enough dry storage to keep it in good shape during the 2-3 weeks it takes to paint it. We worked out a deal for him to paint it, that's why I'm taking it to indy  instead of staying local.

Locally everyone quoted me between 15-25K to paint it. Which just flat out isn't going to happen.
This guy's quote is much more reasonable at 5500-8500 depending on how much stuff they have to remove and repair.

Still a chunk of change but much more in line with reality I think and they do great work I've seen some of the other stuff they have done.

Tim,
Actually the Stripes paint job was what we were originally going to do, but after playing with it in photoshop a bit we decided on the inversion of the stripes job. Green on top white on bottom. For some reason we just liked the look.

Here's the side by side of the basic layout without the upper stripes

Title: Re: 1976 GMC Motorhome
Post by: SONIC. on May 13, 2017, 10:32:17
Barto,
Yep some of them had rear baths with a sitting tub like that in there. It's a tiny tub but it's there haha (the one irk posted I don't think is a GMC I haven't seen one with a full size tub before). Those models sacrifice a lot of more usable space in favor of the big bathroom. At 26' long it's really pretty small but done correctly you can make it feel big. Everyone that walks in mine goes "whoa it doesn't look this big from the outside".

Should paint it like a phone booth and call it the TARDIS hahah

Post by: SONIC. on May 18, 2017, 09:22:23
Made it!
Had one little vapor lock episode but hit the switch for the external fuel pump and that cleared right up.

I think it was the windiest day in history. The thing drives great at 70 when its calm, but throw in an intermittent 30mph crosswind and it gets "entertaining" to say the least. Every bridge crossing tried to kill me, as did every break in the trees.the semis were all over the road too but it still was  not fun. Next time I have to drive in those kind of winds I'll be driving to the nearest gas station, buying a 12 pack and proceeding directly to the nearest state park for the remainder of the wind hahah.

It was a frustrating 5 hours. Wind was from west to east at ~30 and we were heading due north. The few times we turned east or west it was great, then we'd turn back north and i'd want to just run it into a pole  ;D

Better suspension and bags will help a bunch to keep her steady in the wind. Kind of a sweet spot between ride and steady ride but maybe someone has a formula... like weight plus wheel base X height = 1210000

Bags would be good because you can quickly firm or soften to help the ride.

The suspension is already air. Adjusting does help and it's okay in a steady crosswind, its just when it goes from 0-30mph it's a nasty surprise ha. I got good at watching the trees to know when the wind was coming.
But I do need to do some more experimenting to get the ride exactly where I want it.

Stainless won't help you with the aluminum because of galvanic corrosion.
Title: Re: 1976 GMC Motorhome
Post by: SONIC. on May 24, 2017, 18:47:44
This is true, but only to a point IMO.
A stainless fastener with some antisieze will far outlast a steel fastener even in aluminum. The problem isn't the aluminum corroding it's the steel rusting until it's too brittle to remove.
I could be wrong, but it's served me well so far

Trek, sorry I forgot to give you a heads up when we went and got it, I remembered about halfway home! Barber?

Made the 5 hour drive in style with only one issue, vapor lock caused by a stupidly designed fuel sump (not my design) so I drilled a hole in it and routed a line back to the tanks so now the pump is always recirculating and will keep the fuel from boiling.
Lots of positive comments at the gas station and lots of thumbs up on the road. Way different than the "who the fuck would drive that POS?" Looks that I got on the trip up there haha.

Plugging away here, down to the wire. We're leaving on the 10th!

Got the exhaust mostly finished up today.
Started here:
(http://www.thegmcrv.com/wp-content/uploads/2017/07/IMG_20170702_105908753.jpg)

A lot of cutting and welding and tube enlarging (for slip fits) later and it's about complete.

(http://www.thegmcrv.com/wp-content/uploads/2017/07/IMG_20170703_124759649.jpg)

Long tube headers, to 2.5" collectors, into flex couplers into the Y pipe with a 3" out. 3" all the way back from there to a muffler in the rear.
All stainless.
Turned out great, lots of work though. Super sore from climbing under and out from under this bitch probably 300 times.

ALso mildly deaf after having to drive it in and out of the barn with open headers. holy SHIT a 455 is loud with open headers.

Well were underway!
Tons of problems so far but they have all been solved. Yet another reason to learn to do shit on your own! We would have had to have been towed within 30 miles of home, and then again 100, and 200 etc. But here we are 1000 miles from home and still trucking g working out all the kinks. This is also what happens when you don't have time for a shakedown run haha. Probable equal time driving and wrenching so far. But tomorrow should be a good day I think it's all fixed!

Nice, enjoy and I agree on knowing how to fix your own shit, I watch folks pay hundreds or thousands to tow and fix a bike that died on the road that I could have fixed for pennies LOL.

No, no...sarcasm was meant.

Just reading through the thread and not noticing the dates, made it seem quick.

You stuck with it, and did a great job.

I have bike projects that took longer than that and they were a lot less work. That is seriously awesome.  I am impressed by the work you did on that.  Can we nominate it for BOM?

Hugely appreciated guys. It's nice to hear good things from people that I know can make their own shit!

And the knives go in the cabinet for travel haha. Don't want to slam on the brakes and avoid a crash only to be run through by the butchers knife flying through the air.

AAAAND we made it home.
5000+ miles, a few issues and a great time.
Officially a married man as well.

Things I learned:
Driving in a motorhome rather than a car is great. A lot less cramped and boxed in feeling. That being said the drive from Glacier NP to TN is NOT a fun one. 3 straight 12hr days sucks, car or MH.
Roads through Indian reservations will rattle the teeth out of your head, if they are paved. Half of them are not and are worse.
Don't attempt to climb 10% grade gravel mountain roads in a 40yr old 30ft beast. Yes we made it, but it was not fun.
Don't travel without a motorcycle  8)
