I'd talked to Carlisuspension first. They will probably have some ideas. Probably the best way is to go to large, 12.5, 37 inch tires and air them down. Going to longer travel, lighter load springs and shocks probably would help as well. The Ram Power Wagon has a much lighter load capacity than the standard 2500's which is probably a clue.
I know what you mean. I've got an 06 Ram 2500. E
