This is my favorite project on DTT.  I always liked to look of those things and while I have no good reason to ever own one, I do covet your.. :-)

Thanks teazer, it's funny because I have no need of one either!

Cx, do you happen to know his name?

I get not knowing, but I can't for the life of me understand not trying. It's only metal it can be fixed. Man up and risk a mistake in exchange for a lesson.

I get tons of old man jokes from my buddies, but I'll be the one laughing when she's done!

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.

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 man joke is pure jealousy. I love those things even before you bought one and started making it awesome. Keep it up buddy!
