There is an upgraded king pin which will greatly improve your ride available as a replacement for your MORryde, though not a Trailair. From my research, your MORryde RPB72-2210031 was a replacement for Dexter pin box 221-0031-00 and the upgrade replacement which fits is the 5th Airborne Premium # RP61452 from Reese.

This is similar to the Trailair in that it greatly reduces the amount of chucking and jarring you'll experience when towing, and uses an air bag to help deliver a smoother ride. The 5th Airborne also moves the pivot point 22" to allow for more turning clearance and a trailer which tracks your truck even closer.
