I have a 2005 Durango fifth wheel. I also have a 16K Drawtite Slider Hitch. We have pulled our trailer Approx 50-60K Miles. and our hitch is very sloppy. Little wear here little there ,lots of points ...
I used to have a 2007 Durango before I purchased my Cameo. I had a 16K Reese hitch. It was not a slider, as I have a long bed, but it was a great hitch. If you want to stop pitching and your hitch in the truck is good, then I would look at a MorRide pin. I have one on the Cameo and I noticed the difference in towing right away compared to the Durnago's hitch.
