Ok here I am... The reason we sold ours, are as follow, the weight, the bulk when packed, and the floor layout of the 10x10.
The way the stove is placed in the tent, is almost centered, so you can sleep one on each side for two... Good for two buddy's, but kind of boring for a couple.... If you need to sleep 3 in there, then one is in front of the door, and that is not practical for any length of time, other than maybe an over night trip.
The ventilation, is great, they have a vent tunnel about a foot from the ground beside the door(fresh air intake, and one on the back wall opposite corner up hight close to roof line(moisture/"bad" air exhaust).
Since the tent is a double wall construction, the moisture tent to build up on the inside of the fly, that is great, so no moisture inside the tent even at -40 wile cooking inside.
You can rig some line inside the tent along the roof line... That said, in the 10x10, you end up with a lot of things in the way. It is actually just over 9x9 inside at the floor seams, and if I remember, it is maybe 5x5 at the roof seams.
The other down side to me is the fact that it is a really dark tent, even during the day compare to a "white" canvas tent. The Wall tent type tent offer way more usable/living space inside. It is way brighter inside.
Like I said, the AO are really well made tent and now with the vestibule option, make a great tent even better. but just doesn't suit our need anymore!
Hope that help. If any more questions, just shoot, I' ll try to answer them as best as I can.
Cheers
David
