Hello All, I just bought a new truck (an F350 CC 4X4) and it is considerably taller than my previous two wheel drive truck. I installed my 5th wheel hitch in the truck this weekend and hooked it up to the camper. On level ground, I have right at 5-3/8" of clearance between the top of the truck bed rails at the rear and the underside of my 5th wheel camper. Does anyone know what the "ideal" clearance should be? I can raise my 5th wheel drop hitch about 3" to get more clearance if necessary but the truck and camper may not be level then. Thanks for any help and/or info.
