I have the same issue. I hooked up and retracted the legs. I lowered my hitch down one hole to get the nose down a bit. I measured and i am sitting 6 inches nose high vs rear bumper. I have just under 6" bed rail clearance. Really doesn't look unleavel. I contacted Forest River and they said that was not a problem. I also have a 2014 2500 Ram CTD and a Rockwood fifth wheel with a Revolution pin box and a Reese 16K Pro hitch on a picture frame adaptor. My truck settled just over 1-1/2 inches if I remember right. I have towed it only 100 miles with this truck and no problems.
Correction, after looking at my photos the truck settles 2".
