Yesterday I decided to tow my 30ft camper(6400lbs) to our sportsman's club. I was real disappointed in how my truck struggled. I know the lift and 35's sucked some power away, but I could not believe how much. I'm hoping it had something to do with me not using the correct tow setup. I could not use my weight dist. bars bec my hitch did not have enough drop. The one I did use still left the camper a lot higher in the front than the rear. Do you guys think this made a difference? Looks like a gear upgrade in the near future.
