We have a Hickory edition and they seem to have a lot more insulation. we had ours in 13 degree weather this winter and had no problems keeping warm and the furnace did not run all of the time. we also used a couple of quartz heaters. there have been some on this forum that have spent winters in the cold, i am sure they will be along. Contact Wayne and carolyn Mathews, they are in Montana and I am sure she has some good hints.
