Looking for ideas with bedrail clearence on 2013 Ram 2500

I have the 3500 and didn't like the raised rear so I took a couple of the spacers out of the rear suspension. It lowered the rear bumper about an inch. I want to address your comment about the slider hitch. Although we have a slider hitch, we don't need it because the nose of the trailer is sculpted much like the nose of your trailer. Sharp turns are no problem other than watching the pin box to make sure it clears the bed rails.
