This is our 2nd Trailair hitch and I'm still not sold on them. I also have had a Mor/Ryde pin box its a excellent pin box. I will say we had a Trailer Saver air ride hitch which is a real air ride hitch so I'm a little spoiled. If we were still full timing I would get another Trailer Saver Air ride hitch with the Mor/Ryde pin box. But for now I will stay with the Trailair pin box ($$$), it does help the up and down but now the side to side or front to rear. We have the Trailair Center point suspension and I do like it.
