I ordered a 200 board foot spray foam kit and today I spray foamed the frame rails to help conserve propane in winter camping. Two weeks ago while staying at our daughters home in Belgrade, MT we were going through 4 gallons of propane a day and the furnace would hardly ever turn off with the thermostat set at 68 degrees. I have since purchased reflective bubble wrap for the windows and now I have spray foamed the frame. In my opinion, this should work better than skirting. The coroplast has a foil barrier and then two inches of fiberglass on top of that, but no insulation at all for the frame rails. That is one hell of a heat sink when the frame rails are in the teens, the heater has no chance of making that area below the floor very warm. Stay tuned and I will report how well this works.
