My Class C is Canadian built and I've made lots of cold weather modifications. Here are a few:
electric heated carpets
two auxiliary shore power cords (20 and 15 amp)
Fridge protection using a 60 watt bulb and a TC-3 thermocube
extra insulation
heat for the waste tanks
dual window fan to replace the cold air return grill for the furnace.
Electricity is included in the campsite rental. Propane I'd have to refill every 3 days. A Mr. Heater is NOT safe to use as it is an unvented combustion heater. My daughter is a CO survivor. I will never use an unvented combustion heater.
I keep my continuous load electrical use to 80% of capacity or less (2880 watts for 30 amp, 1920 watts for 20, and 1440 watts for 15 amp). My peak use is around 7000 watts.
I have used my RV at -37 c (-34 f)

RVs are not meant for those temperature, maybe an Arctic Fox. Why aren't you using propane? As a future reference I would get a Mr. Heater for those temperatures.
