I have a 96 gmc 1/2 ton with a vortec 350 not sure of the gears. Does anyone know if my truck came with a trans. cooler from the factory or how do I check to find out. I just bought a 26 ft. aerolite that weighs 3595 lbs and would like to know if a weight distribution bars and sway bars are needed or can I get away with just a sway bar.And if anyone has advise for a true newbe on anything please let me know the ins and outs. I have to go 680 miles to pick up the camper and would like to get as much info as I can get before I leave in two weeks. Thanks, Chancy
