Hi Paul,
I've camped at -37 C (-34 f) and boondocked at -27 (-16.6 f) in blizzard conditions for five days. My solar did little for me. I did run a generator for about four to five hours per day. That RV had two Marine batteries from Walmart totaling 250 amp-hours. I did use the four stove top burners as a blue flame heater when I was NOT in the RV.
Replace the return air grill on the furnace with a fan. On my rv that circulates warm "living space" air under the cabinets and pushes some air along the furnace duct work. I chose to use a dual window fan unit which is controlled by a mechanical thermostat that lives beside the water pump next to the outdoor wall of the RV.
The fan unit draws just 23 watts and works better than a 1500 watt fan based heater which I tried using inside the cabinet.

It may be necessary to protect the fridge from freezing up. I use a TC-3 thermocube which controls a light bulb in the external compartment.
I won't use a combustion heater inside an RV. My daughter is a carbon monoxide survivor.
I won't run a generator while sleeping for the same reason.
Read this thread to find out what I did for windows, vents and skylight coverings and some early results. a fix for winter
This is just my 2nd night with my new covers.

Steve -
I noticed that the water pump and most of the lines run along the interior floor, behind cabinets. I'll probably buy a small electric heater (200w) to warm up those compartments.
