I've been told (don't know if it's factual or not) that the newer trucks don't articulate as much (cab to bed movement in off camber situations) then older trucks. I do know my '97 F350 moves alot. Again, been told the frames are stiffer so articulation is less, consequently, cab roof to camper cabin over clearance can be less as well.
My Palomino has a gob of cab to cabin over clearance. so much, I'm considering some type of air dam between the cab roof and the camper. I have about 8" and that is with the camper sitting flat on the bed with nothing in between, which, is how I run it anyway. The Rhino Lined bed provides plenty of frictional grip on the bottom rails of the camper. Has never moved at all.
