Fitting the 240V Generator
I haven't seen the bolt on exhaust. Sounds like a good idea.
With the small back door open, it could run all night and nothing on the truck got hot. They blow so much air around (a lot of the air coming out of the exhaust vent is 'fresh air' - it's not 100% exhaust gas).
You could put your hand on any part of the body and it was nice and cool.
