When I replaced some rotten flooring in my first Airstream I decided to replace the pink stuff with foam sheets. I made the floor repair with marine plywood, but I didn't remove the belly pan, and trying to attach the foam sheets to the plywood, and then putting it down was not an option because of the frame with all the cross members.
I thought about it for a while and then I hit on the idea of gluing strips of the foam cut into strips together and I attached them to the four sides of each cross member at the depth to allow me to suspend the foam sheets also cut to fit each section, simply by laying them in on my "shelves". I made sure the foam was at the right depth so when I put the plywood down it touched the foam, leaving it up off the belly pan making a nice air space. In my mind the only way the foam could get wet would be if the trailer leaked again...
