I really do not think so. After my trip up to Wisconsin's Door County and Duluth and the Minnesota north shore, and back, I encountered a lot of really bad interstates. I think I-840 on the west side of Nashville was the worst. Each end of the bridges were terrible, as you say, launching you almost airborne.
My truck has Rancho 9000 adjustable shocks set to about mid setting, the trailer has shocks, nothing seems to help.
I've been on the Airstream AirForum (an RVLife forum) and specifically the hitch and tow vehicle forums. They discuss the Gen Y cushioned hitch, the Shocker hitch, and the
Air Safe hitch, all of which you can connect a weight distributing hitch to.
Lots of praise for the Air Safe, with many long time users, the disadvantage being the weight. but I am seriously considering it.
