I read an article about a fellow who wanted to winter over in Alaska in a small camper. He skirted it with foam insulation sealed it as best he could. As the snow fell he shoveled it up to the windows with snow. It looked like a tin topped igloo. He had electricity, burned an enormous amount of propane, survived unscathed and wrote an article on his adventure.
He also had family close by, so we was not isolated in case of trouble.
Can you do it, yes. Can you do it easily and cheaply no. You would be better served to park it and rent an apartment.
