Well as far as the dodge, the dodge is a 2nd gen which means it has waaaay less power than the new gm. They should have used a new dodge with the new gm, the gm may still have one but at least it would have been a fair fight!
Wheelbase, tire size, transmission, and most of all driving style would play a role in who won that. I'd think that the SWB dually had an advantage because of wheelbase... Still neat.
