FYI: Most all makes of the 3 trucks, GMC, Ford, and Dodge, it makes no difference in engine or transmission if you go from 2500 to 3500, the biggest difference for the higher towing ratings is the stability of the dual rear wheels, and the springs are probably a little heavier. This is a very common misconception, not just picking on this poster
