2blackdogs: Bob, your question to Nelson about his hitch and his pinbox having air bags is getting an answer from me as I have both.
I've had the Trailair pinbox since the trailer was new and just recently changed out my hitch in the truck to a Gene McCall AirGlyder with two vertical support bags and two opposed fore and aft bags to cushion take off's and stops. I test towed with both still active to Quebec City and back (about 800mi round trip) with no problems. A "suite" set-up.
