There have been a couple of wood fired external boiler ideas posted but you could also very easily use a propane water heater and a automotive heater core with a computer case fan!

I have 2 identical sleeping bags from years ago that I can unzip each of them completely, and then zip them together to make one big one. It works pretty well.

Two layers of canvas with a layer of flexible closed cell foam in between. Use the same type of foam that is used in the thin sleeping bag pads. Where it needs to fold, run a stitched line, or make a gap in the foam and stitch down the middle of it. You can offset the stitched seam to make folding easier. It likely would be best if the inside canvas is breathable so the interiors of the walls can dry out. To hold the foam in place so it doesn't migrate, flexible foam to cloth glue could be used. I don't know any brands, but I know it is available.
Years ago I read some comments made by a guy who did this for his pop up camper. It cut the furnace run time by over 70% on cold winter nights. He only used 1/2" closed cell foam. If it wasn't for my hard sided requirement, I'd use this method.
BTW, this should also cut down on flapping in the wind. Especially if the foam is glued to the canvas.
