No problem if you have the Dometic or similar Thermostat that automatically
kicks in the propane furnace if the outside temperature drops too low (I
believe it's below 30-32 degrees F). There's also a manual setting to run
off the furnace.

Thanks to the EPA most exotic fluorocarbons that would offer atmospheric heat extraction below 30 degrees are banned.
