...I came across these pics I took of un-mucked with 2K1 bodies at the time I was restoring Dennis' old truck. I hope they can be of some assistance.

First is the inside of the generator 'fridge'. Note the two way exhaust fitting on the floor. Also of note is the rack on the mid rail for the 12V Johnson chorehorse. It's very similar to that in the HUW and consists of two rails made of 1" by 1/8" angle welded together with a gap big enough for a 1/8" in plate. The chorehorse was bolted to the plate and the plate slid into the rails. You can see a small pin and chain on the tops of the rails which were what keeps the plate and chorehorse in place. This arrangement allowed for 'quick release' of the generator to allow it to be operated at a distance from the vehicle.

There isn't a similar rail assembly on the bottom and I am of the opinion that's proof there was a 120V Onan in the lower part of the generator cabinet as standard in 2K1 bodies.
