Right truck and camper setup for a northern Alaskan winter

Have camped in Alaska in -20F in our Bigfoot 2500. We were warm but shot through propane like water. Also, -40 is a no flow in the propane. You would need hookups and an electric space heater as well as bottled water for that (so as not to burst pipes in basement that gets no heat without a furnace blowing. It could be sone with a homemade build designed for winter and a mini wood stove.
