I was going to post and say "Oh my god here we go again" but I couldn't answer your question so I didn't post. I can't tell you of a park but I'm laughing because I imagined your post getting off track and into the "YOU CANT LIVE THERE IN THE WINTER" type conversation.
But, you did say you have been in it at -20 so you know more than a bunch of us I guess. Sounds like a challenge to me but I wouldn't say it's impossible. It's just a matter of energy use vs ability/willingness to pay those costs vs renting. My basic stance is I'd probably lean toward making an RV work compared to an apartment. I dont know Alaska but it's probably hell in the winter and a real beauty in the good months.
