Pin box hitting bed rail

My pin box has a cover on it. The other day the cover hit the bed rail on level ground. I have 5.5" clearence between the camper and bed rails. The truck is a 09 gmc sb cc 4x4. Any ideas what to do. I removed the cover and that gave me a little extra clearance. What else can I do?

I know where your comming from cause I have a coachman! Mine has that same pinbox cover and mine hit the bed rail as well. My dealer trimmed the cover back and I raised my hitch two holes and that gave me plenty of clearance except in a hard turn with the truck leaning (rare). Good luck and enjoy your Coachman!
