when plugged in to shore power, i use 3 metal drop cord trouble lights with 100w bulbs, 1 each, in the water pump compartment, the main water tank compartment, and the aft water service compartment. a 100w bulb puts out about 300 btu's of heat. when not plugged in, the propane furnace should keep the tanks and lines from freezing. i also run the propane water heater as necessary to keep the water pump compartment from freezing when not plugged in. i have 3 remote sensing indoor-outdoor temperature gauges to monitor the basement compartment temperatures, from walmart and harbor freight. i used wire type temp gauges, but wireless are easier to install and are available for a little more $. when plugged in to shore power, i use 2 thermostat controlled 1500w fan type box heaters in the moho, mostly set on the low 750w setting.
if i remember correctly, electricity in canada is mainly 220v. i don't know how you would deal with that in an rv.
