I was thinking of the gear ratios and weight differencies but i still think that the engine is "underpowered" because even before all my modifications with stock tires had difficultiies going up on some larger longer grades.Most times i had to shift back to at least 4 th or 3rd gear to go up and keeping a steady speed/meaning not slowing down/.I know it is a heavy suv but the other truck would have no problem at 5th gear.So i am deffenitely going to look for a scale around here and check the weight and also look up the gears on them and post it up.
