The combination of the Trailair pin box and the Curt hitch is not a good one. I experienced severe chucking when I first tried to two with the setup. The pivoting geometry of the Trailair pin box and Curt hitch caused the problem.. See my calculations that explain how.

I chose to change the Trailair pin box for MORryde rubber pin box and have enjoyed a good ride since. I could have changed the hitch but that cost more and I didn't like fussing with the Trailair air bag. If you decide to change the hitch, get one with the pivot point of the hitch head close to the top of the hitch. A B&W would be good good choice.
