I've had mine (12x12 w/ vest) for about 4 years and spent over 100 nights in it I bet. We used a wood stove. 4 guys can sleep on cots in it comfortably, but 1 is near the door. Gear under the cots and in the vestibule.
Some things I have learned:
1. Clear the spark arrestor every couple days. Ours plugged in the middle of the night and smoke filled the tent. It was unpleasant
2. Duraflame logs are amazing for putting in at night so you can sleep 3-4 hours before stoking it again.
3. Be careful around the stove. This goes without saying, but we have melted a jacket and sleeping bag on the side of it.
4. We used 500 cord and bungees and ran it between the corner loops in the ceiling. This makes for easy gear drying.
5. The floor saver is definitely worth the money. Hot coals/sparks will inevitably hit the floor. That canvas floor saver doesn't even get a mark when they hit. It is heavy and bulky though.
6. After 2-3 days of camping on the ice you will have a giant puddle under the tent. It is best to get some heavy stuff out of the tent and just slide it over imo.
7. It is a pain to put up/take down in the wind. I would really avoid that if you can. Take two people to set it up. 3-4 is much easier/better.
We enjoy ours quite a bit. I made the stupid stupid mistake of stepping in it with my damn cleated winter boots and made a few tears in the floor, so i need to take it in and get it patched.
