It has air ride suspension even with that said, I plan to replace the stock pin box with an air ride version for the very reason you just mentioned. At the moment, I dont go much much more than 300 miles from home in any one direction and I have been careful about staying on good roads, but I definitely plan on a cushioned hitch in the near future.
