I recently purchased an Airsafe hitch from Lloyd at https://airsafehitches.com/
The customer service was exceptional and he answered all of my questions promptly. His follow through is great!
The AirSafe hitch works fine with my weight distribution system. I also have Towtector rock protection. My nephew owns a machine shop and he customized them so they are now welded on to the Airsafe hitch...it's all one system now. I use a Pittsburgh Automotive transmission jack to move the hitch around and to attach the hitch to the tow vehicle.
Gone is the bouncing, jerking, pulling from the trailer and truck combination. No more bumps and porpoising from highway expansion joints. The Airstream, literally, glides down the highway on a cushion of air.
