I installed the MORryde box 2 summers ago while heading up into Nova Scotia and Newfoundland. I put 12,000 miles on it on that trip - - love the difference it made in reducing chucking. Then, this past summer it was up to Alaska. However, I had problems while in Denali and limped back to Anchorage with pending failure of the kingpin framing. The front framework was cracking but luckily I was covered under a call back. I determined I would have an air hitch also to help prevent that from happening again.
I have since purchased the Air Ride Hitch (http://www.airridehitch.com/
) because I don't ever want that happening again. I use it in conjunction with the MORryde box. The ride is fantastic. If I were doing it all over again, I would only buy the Air Ride hitch. If you look at their website, you will see that hitch is a fully air suspended (four bags) hitch allowing it to move up/down and fore/aft plus some side movement. It cushions the chucking as well as the up/down motion. The Trailer Saver is a hinged hitch, meaning it has a swinging arm up and down mounted on a pivot. The up/down motion is cushioned with air bags, but the pivot prevents the hitch from moving fore/aft to kill the chucking action. Reducing the up down motion definitely helps the ride but does not seem to kill the chucking as much as the Air Ride hitch. If I were buying a Trailer Saver, I would also want the MORryde pinbox to reduce the chucking.
I went for the 25K hitch even though I didn't need one quite that big - - the 25K unit uses the Binkley head. It is so much superior to the standard hitch heads I felt the extra money was well spent. I have not been disappointed at all. That head is what is used on OTR trucks - - the jaws are huge and the locking action very positive. Hope that helps.
