I use one most of the season. It's nothing special and I bought it cheap. I use an electric heater in it. If you are staying at a campsite that has electricity, this is the best way to go. Stays warm, and does not cost anymore, since you already paid for the campsite. I've stayed in mine in some really nasty weather and remained comfortable. I also love tent camping, and have done it for years, but to be honest, when it gets cold here in Illinois in November, I like coming back after an all-day sit to a nice warm camper.
