"The Man" is considering some type of sheet of insulation between the frame and plywood floor. Something he came across at Lowe's. Comes in 4x8 sheets. Any thoughts? Has anyone put insulation under the floor? We're in a cold climate.

We remember someone from the old VSTF that insulated the floor. Don't know if s/he moved over here though. There is no reason not to insulate if you're in a cold climate, our only question is whether it would cut the inside height down another inch (or however thick the insulation is. In some of the larger models, it might not be a big deal, but the Compact is only about 6 feet high inside as it is, and for a taller person, that half inch could make a big difference.

Also will it stand up to the load or will it compress and let the floor bolts come loose. I think if I wanted the floor insulated I would go with insulation below the floor between the joist and a belly pan type setup.

Maybe 1" Styrofoam sheet cut to fit between the frame rails, then covered with a 1/4" plywood. The thin plywood would allow you to just screw through it and into the floor plywood, and it would secure the foam.

My concern is the compression as well........................ "Under the wood flooring", NOT "on top of the steel frame".
The compression then becomes a "non issue".

I used sound board 3/8" thick 4x8' sheet purchased @ depot. Just removed & replaced what has worked from the factory on a '56 shasta (granted they installed it in oh about 15 pcs). It was between the frame & ply wood. No problems with compression. I also hit the bottom with henry water seal.

I am in a cold climate as well. I was thinking about cutting out the belly pan and using spray foam, then replacing the pan with ABS plastic or sealed/treated 1/4in plywood...
Any thoughts?

Hmmm... I hadn't thought of spray foam in a belly cavity but if you've got supports to maintain the integrity of the structure, it might be OK. The thing is, any and all compromised floor framing/joists must be sound or replaced before such an action. If there's rot, it's got to be fixed first.

My camper has 1-1/2 inch foam between the floors framing, it had 1/8th in. plywood for the belly and 1/2 in. for the deck. I use this camper mainly for ice fishing during some might cold weather, down to 20 below, the floor stays toasty and warm, even in my stocking feet. There too was these square tile sized carpets stuck to the floor. I think that also helped with the insulation. When I get it back together, I am going to install linoleum and cove it up the walls an inch or so, then get some throw rugs so I can shake them out from time to time and still have that carpet affect for insulation. There too was 1-1/2" foam cut to fit between the wall studs and supports. Also, this foam had an aluminum foil backing to reflect back in the heat. In the walls and also on top of the floor structure, under the floors deck. I am going back on with Reynolds Heavy duty aluminum foil, or tin foil, whatever it is, with the shiny side up on the floor.

In Canada where I live we can order our new trailers with a heated and insulated underbelly...

So, the 1.5in foil backed foam works well out on the ice? Did you cover the foam under the trailer?

I have a pic. of it with the top deck pulled off, it shows the foam between the structures. When I get to the house I will post the pic. There was no foil on the underneath side of the foam, just on the top side of the foam, under the 1/2 in. floor deck the pic. O have I had removed the foil, it was in little squares about a foot square.

Here is a pic. of the floor structure and the insulation. There is a couple of pieces of the foil still down. IMG_2830 by Martin Draper, on Flickr
