It was -42 F here on Lake Vermillion Cook, MN this morning. It has been -35 F or better for 5 days in a row now. The windows frost up as soon as it hits -20 F. Have placed hay bails around the perimeter of the trailer and piled snow up on the hay to seal it off and add a little extra insulation. Also placed a 1000 watt heater underneath just for added security. Also run two 1000 watt ceramic heaters indoors to conserve the propane. Had to utilize a 100# tank to increase the surface area of liquid propane to vaporize in tandem with a 40#. I toggle the regulator switch about every 8 hours to prevent the valve from freezing up. I am thinking of changing regulators to increase the size of the lines from the tanks to 3/8". Anyone done this before and have successful results? I use about 100# every 10 days as it is. When it is warmer, lets say above 15 F, I get about a week out of a 40# tank. This is not the most mobile setup and I had to run a 240 volt cord and split it to two 110 volt lines to support all the electric heaters. I melted one plug end before I added the 240 volt. You could do without the hay bails if you kept a few pieces of 1 1/2" high density foam insulation to cut to size for the perimeter of you AS. It would take about 2 to 2.5 4' X 8' sheets to go around a 31'. This setup provides more leeway for breaking camp. But I am here for an extended stay so the hay bails provide an R-value of 400 as opposed to 20. Oh I also ran an 800 watt heater in the rear bumper for the waste line. I only need this when it is -30 F or worse though. So. Winter camping at its best. Expect quirks to work out. Sometimes on a daily basis. Also with my AS if I leave for more than a day it is a crap shoot because the propane freeze up under a heavy load and the furnace fails to ignite. I have had to repair a burst water line.
