I've never used a tent heater, we've actually never had to use the back-up sleeping bags we bring. Having the down comforter below us with a very heavy wool comforter makes a snuggly bed. We also don't use the tent for anything but sleeping and changing clothes. Hangout time is for the easy-up.
Fred, whats the small stool for?
We use the stool early during the day as a foot rest and or table.
When it gets crowded near the front we stand on it to get a better view.
It is only 6" high. We are both kind of short.
