We were out the same time North of Nordegg. We have a propane furnace and a Cubic mini wood stove in our rig. Our Webasto is set up just to heat the engine for starting. Solar wasn't keeping up as we were completely off grid, but I have a 1000 watt generator that I plug in to the sore power and we have an 1800 watt Xantrex inverter charger. Ran the generator in the evening before bed and we were good. Fire up the wood stove first thing in the morning and nice and toasty. Nice thing with wood heat is no condensation issues. We're sure enjoying the warmer weather now, but losing snow!
