    Spray Foam on Frame Rails

    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.

    This may be a dumb question but did you spray the inside or outside of the rails? If you dropped the corollas did you check all the heating ducts? I like the foam idea and fixing the heating ducts will help a lot too. Maybe even replace the flexible duct work with something solid or a little better quality may help as well.

    If there was a way to post photos here I would do that. I sprayed the outside of the frame rails, and also the steel cap on the drop frame. I made sure to seal off as much of the gaps as possible around the slideout penetrations also. I might have to try sticking a probe into the belly to see if it holds some temperature now that it is fully insulated and sealed. I checked the outside temps of the frame rails before with the furnace running and they were only about 10 degrees over ambient temp.

    I believe when you post if you use the "go advanced" button you can attach pics. I think.....

    Hi Nuffsaid,

    There are a few different ways to add pictures. I find the simplest is to hit the "Go Advanced" tab on the lower right of a new post and scroll down to "Manage Attachments" Then "Add Files", "Choose File" and "Upload"
