once you get to the point you can turn over all four good, I think weight is the most important thing in truck/truck pulling, along with durability and of course your hitch point height in relationship to your foe. with your truck you will never be heavy enough(or have enough tq) to take on oil burners, even old ones. I would stick to gassers, I pulled many a chevy 1500 4x4 backwards with my old *****ty dodge ramcharger, it had a wipped stock 318 in it. I pulled mostly on black top, low range 31x10.50s about 150hp I would hold the brake with it locked in low/low until they started too spin, then let up on the brake and floor it ! It would go wwaaaaa and barley spin the right front and pull them backwards, but they were all empty 1500s I simply outweighed them.
