If you haven't pulled the belly pan yet to take a good look at the frame, then I would suggest you do. You just don't know what is down there in terms of rust and rot and its also a good idea to get rid of the old pink fiberglass that holds moisture up against the frame.
I used a mechanics creeper to roll on, the trailer sits on a concrete apron besides the garage. You could also put some cardboard or plywood down, especially if the trailer is sitting on grass or gravel.
For insulation I used some closed cell foam board that I got at HD. I used 3/4" and doubled it up to 1.5" for an R value of about 8. It is held up with 2" decking screws and fender washers that go into the subfloor. I think it does a pretty good job and it wont hold any moisture against the frame. It may help make the trailer a bit quieter too, but thats subjective.
One bit of advice though, be careful if you are wirebrushing the rust on the frame while you are on your back. I was wearing wrap around safety glasses and still managed to get a small speck of rust in my left eye. It was not a fun experience and not cheap either with what they charge for specialist copays.
