Hi we are having trouble with our 2011 3400RL king pin box scraping the top of the side walls of our truck box. We have installed a CURT A30 hitch recommended by the dealer, but we have already damaged the top of the box. I believe that this hitch is not designed for our truck.
We raised the king pin box up on the camper, but is just too close for comfort. I am considering purchasing a REESE 5th Airborne Premium 5th Wheel Air Ride King Pin w/ Sidewinder and Turret - 16,000 lbs.
Does anyone have any suggestions on how to eliminate my dilemma? Any concerns with the sidewinder feature?
