Low Of 1 Degree!!!

If you are hooked to water, fill your water tank and then unhook. If your furnace is propane then make sure you have plenty, close your dump valves. One thing to check is the status of the automotive AC/heat setting. You want to make sure it’s set to recirc instead of fresh air. This can be a big source for cold air entering the mh. Unless you use the front seats while parked, consider blocking off the cab so you have less area to heat. Don’t use the propane stove or oven for heat as it will create a lot of moisture. Be safe.
