Trip to freezing area for a month - concerns

Get an insulated tarp (rectangle) big enough to cut in half and use that to skirt around. Our MH has bay doors so we just lift the door, put a screw where the grommet is and close the door on it. It hangs on the ground by at least 4" and it does not blow in. It's own weight holds it down. Now, I'm not sure how your TT is built - but I'll through the insulated tarp idea at you because it's easy to take it down, roll it up and cart it down the road. Our MH is 37 ft. but the tarp goes just in front of the front wheels and right behind the rear wheels. I think it was used for a flat bed truck before we got it.

We have a small electric heater in the bay area on the MH and for the TC we hung an electric heating pad in there to keep the valves from freezing up.
