Just bought a 32' Camper and could not stand the idea of having the rails in bed for a 5er. Bought a GN adapter with 8" offset. Was $900 total with B&W turnover ball. So glad I spent the money now before I bolted those rails in my bed. It clears my weatherguard across the rail toolbox also. Had to extend the GN adapter so the hitch pin will clear bed rails on tight turn. Had it on a couple trips so far and I am pleased. I am thinking about lifting he trailer a couple inches for a more level stance.
