Bingo, several years ago I saw a bed mounted hitch supported by four air bags; one at each corner. I do not know the brand or if it's still even available but the guy told me the bags were adjustable and he loved it. It allowed several inches of vertical movement. But I have to wonder if the hitch would drop so much that the bed rails might contact the underside of the trailer. Something that muct be considered.

Good luck in your search.
