We use two smaller tents, one for sleeping and one for cooking/hanging out in. Put the two tents front to back and then you can close one door or the other so that you can heat a smaller space more effectively. We use propane for heat. We also take a piece of reinforced poly sheeting that we cover both tents with, on the outside. Allows snow to slide right off and the sheet we use is big enough that when the snow slides off it's not piled up against the outside of the tent.
6 of us this year and we used, I think, a 10'x12' and a 10'x16'. One made by Reliable Tents and the other Montana Canvas.
