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."

Reminds me of...me No, I'm sure of it. I hate him
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)
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.

Not a lot to update, got the plumbing mostly done for the drains yesterday, that's about it build wise.
I applied to be a dealer for the new FiTech Fuel injection systems and got approved yesterday, so I am now a stocking dealer for those (discounts all around woot)
Ordered mine yesterday so pretty excited about that. Pretty cool little units. Fully self contained self learning fuel injection.

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.
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.
