I've watched the Wilderness Family movies. How hard can it be? Make friends with the animals and they'll keep you safe from the ones who haven't gotten to know you yet. Other than that, you split wood once in a while, but otherwise, you smell the flowers and play with the animals, and someone will bring you food in an airplane every now and then. Surely, some old mountain man will come down to help you out in a pinch.
Apparently that is what many think. Just like the "migrants" that came here "because of global warming" according to Kamala Harris, who are now in New York and Chicago for winter and are wishing for global warming to hit there. The latest story is that the migrants who were housed in New York hotels at government expense are now refusing to leave the hotels when alternative housing is found. I guess the American and Alaskan dreams are dead.
I gotta think that behaviour generates macabre local jokes about "iceboxes." These stories blow my mind.
I had a motorhome that I thought about using as a contingency. I love thinking up contingency plans. I was going to put it in the pole building and then surround it with straw bales. I worried that the cold would seep in through the floor more than the walls and roof. Lots of people here put bales around their foundation for such a reason.( country folk not the people in town) I don't know how the people can live in motorhomes and camper trailers in Alaska.
You can lift the carpet in a mobile home, grab a corner of the thin plywood flooring, pull it aside and see grass. I gotta think that motor homes are built to even lower standards to save weight. Regarding using straw bales...I would worry about that one jerk with an attitude and a match.
Most RV exterior walls are 2-2.5" thick. No insulation. There is no way to heat a tin can in those extreme temperatures, not to mention the frozen water pipes, water pump, black and gray tanks, etc. What a nightmare.
I had an acquaintance who moved here from California and he and his family spent their first winter here in a motorhome. He said it was the most miserable time of his life. He talked about the bed covers freezing to the walls, and emptying the tanks was terrible as they couldn't use the hook-ups as they were all frozen. It can be done, but I don't think it is a pleasant experience.
