Homer's weather isn't all that bad (compared to Fairbanks), so an Arctic Fox will probably suit you well. Don't think I'd go with much of any other brand for this. You'll have to skirt it to insulate the bottom, but that's not until you get there and put it where you want. Your water and sewer will have to be heated as well to keep them from freezing. Again, not a really hard thing to do, but you've GOT to have power to your site first. And you really don't want a lot of windows since they let in a lot of cold.
