We need the supplemental heat when we boondock with our snowmobiles, temps can drop below zero. We run the genny every morning and evening to charge batteries, the furnace runs a lot. Always have the heater going to give it a load. We also use electric blanket to warm up the bed at night.
we use a 2 controller queen 12v electric mattress pad from backwoods solar. it works well for us.
i installed 3 indoor-outdoor wired temp gauges, 1 in the water pump-water heater compartment, middle water tank compartment, and in the aft water service compartment to monitor temps.
wireless gauges are available.
the propane furnace keeps the compartments above freezing. when on shore power/genny, we use 3 750 watt box heaters in the coach. we use a 100w trouble light in the middle and aft water compartments. we found that the fwd water pump compartment stays toasty when the water heater is on with the electric element or propane. otherwise, i would use an additional 100w trouble light.
