We just got a new tow vehicle. A F-350 6.0 super cab, 4x4, We have a 2900MK. After installing the hitch and backing up to the camper a concern has come up. Being the truck is several inches taller than my previous tow vehicle we noticed that after all hooked up and the landing gear retracted my camper no longer rides level. We have approx 6-7 inches clearance from the truck bed rails. My questions is how low can I go if I lower the hitch height and still have a safe clearance between the bottom of camper and the bed rails. I can lower the hitch a few inches but dont want to risk bringing the camper closer to the truch bed rails, should i just tow with the kingpin higher and not worry about the trailer being level..Thanks
