I spent the winter of '93 living in a Tipi in Upstate New York (actually, I spent the fall/winter of 93 and the spring and early summer of 94 out there). I know it is not Alaska but -20 is -20.
It was a canvas tipi from Panther Primitives and it worked amazingly well. Rain, wind, snow, and even some really big snowfalls didnt phase that thing. I had a great fire in the middle of the room all the time. Cooked food, scraped hides, dried meat, and even got laid by the life giving fire in the center of the round room.
I had saws, oil, kero, and gas stored in the utility lean-to about 6' away from the tipi. Didnt need batteries as I didnt have anything that needed them except some flashlights and my girlfriend at the time brought those out to me on visits.
I suppose everyone has their idea of the perfect camp.
"Who are the militia? Are they not ourselves. Congress have no power to disarm the militia. Their swords, and every other terrible implement of the soldier, are the birth-right of an American...(T)he unlimited power of the sword is not in the hands of either the federal or state governments, but, where I trust in God it will ever remain, in the hands of the people." (Tench Coxe, Freeman's Journal, 20 Feb 1778)
