I tend to take a larger stove and smaller tent in the winter if possible. The insulating value of snow is very good. I know this past weekend there was a couple inches of snow on the tent at 2 am and it had been 4 hours since the last load of wood, and the temp inside the tent must have been near 50 while outside it was in the teens.
To bad you can't count on that or that I can't find a reliable way to engineer it. I do have a couple ideas though, but it requires deep snow.
