Does anyone tow a 5th wheel with a Andersen Ultimate hitch?

Did you install the 5th AirBorne to correct a "chucking" condition? If so, did it smooth out your ride? It depends on who you ask, but some manufacturers do not recommend using a air bag or rubber pin box with a Andersen Hitch. I don't get it. Many of them consider a AU hitch as a gooseneck adapter, which it is NOT. The AU hitch is NOT A GOOSENECK. It simply adapts the pin with a ball at the pin box. I don't see why a MORryde or Demco, or TrailAir wouldn't work any differently than with a regular 5th wheel hitch.

It could be leverage combined with fulcrum shift. The adapter from kingpin to ball socket looks to have about a 5" offset. Look at the Andersen video where they install it on a MORryde pin box. The support point is now in front of the front pin box isolators. This means that all of the pin weight is on the front isolators and there is probably some negative weight on the rear isolators. The pin box isolation plate probably wasn't designed to operate that way.

With the increasing popularity of the Andersen Ultimate, MORryde should develop an Andersen specific pin box. The included ball socket could be centered on the moveable plate so that the dynamics of the isolation system would be correct. No more adapters and offsets to mess things up.
