B&W 3400 Slider. Does it Clunk...work in Ram Puck system?

I have the same problem. My 2015 DRW is almost 4" higher at the tailgate than the 04 DRW was. I am running about the same clearance between the bed rails and the trailer, so lowering the trailer by whatever means is not an option. Trading is also not an option; so I will either raise the trailer at the axles or run nose high.
Several on the forum who have traded for later model trucks and kept the older trailers are experiencing this problem.
