Hmmm, the 36 with a 90s to early 2000s pickup frame and diesel.
I have a '94 Cummins 2wd dually if you want to try it, body is kinda rough but its a strong solid truck underneath.
Actually it only has 180.000 miles on it, so I've decided to flatbed it and repaint the cab and just drive it. The box has the worst of the damage, I used it for a hauler for 15 years... engines, transmissions, pipe, valves, etc. It's been hit by more than a few forklifts.
