I LOVE crew cab long bed square bodies. I plan to lift it, good meaty tires, 4X4, manual transmisison. Now I have a question for the powerplant. I know this is a chevy truck forum, but in all honesty, should I have a 12v(or24v) infront of the manual or should I go for a duramax?
I personally like the cummins diesel, but I'm by no means a diesel expert.
