If the vents are clear you can run the furnace in transit.
www.ultraheat.com Combo pads work on 12v or 120v. Install is easier before the cover goes on.
My thread on circulating hot water.
Newest update: Connected a relay so when the furnace cycles on so does the pump. Manual switch also if desired.
For a real expedition I would also carry a third propane cylinder.
Ditto on all of this. Been there, done that; Northern Michigan to Death Valley, mid December through mid January.
Furnace on, all the time. Water heater on all the time. Burns a lot of propane YEP, battling mother nature is not cheap.
I have 240 watts of 12v heating pads on the holding tanks and a lesser wattage of AC heat Trace on the sewer pipes, valves and pump water line. A 100 watt bulb on a thermocube lives in the pump bay.
With temperatures in the teens and below, the generator runs almost 24x7 in the truck bed. Temps in the 20s and 30s I let the battery bank and inverter run everything, charging as needed.
Circulating hot water is a must have for very cold towing in my humble opinion. My system is computer controlled and comes on as needed based on water temp, outdoor temp and forecast temp.
