tent and heat
BushWakr - When we went camping in the cold we would pretty much sleep in heavy clothes and have the dogs under the covers with us. We hung a coleman propane lantern up at the top with the tops of the zip-up windows open, and this would keep the temperatures inside in the low 40s with outside temperature in the 10s. eek: Before I get yelled at, I know that this is not the safest method, and that unburned propane will sink, and we would have been pretty sick if the lantern leaked, but I have tested the lantern for leaks.
So when it's da** cold, I don't know the best thing. There is a company that makes an electric blanket that plugs into the lighter, and comes with an extension, so you could snake it around back. Of course, this would drain the battery really well. Using this tent is definitely tent camping, and you don't get much insulation from the tent.
Hope this is informative
