I have had a Montana Canvas wall tent for the last 8 yrs. It has an internal frame - I purchased the joints and made poles from 1" conduit. It is 10x12. We have had as many as 6 guys in there sleeping on straw and 1 on a big cot and it worked fine, crowded though. I'll second the notion of using 2 tents. We did that the last 2 times out and it works great, especially with the gear that many people can bring along. I have a heavy vinyl floor that is staked down with large spikes and works great, it really reflects a lot of light from candle or lantern at night, and keeps it drier if you set up when it is wet or over snow. The floor came with an area cutout for the stove. I have a rain fly and would not do without that. My smoke hole is on the roof - if I were to do it again I would have the smoke hole in the wall - when it is raining or snowing it will come through the smoke hole on the roof and sizzle on the stove all night long. Make sure to get a flap (with clips or ties) over your zippers on your doors just incase a zipper breaks, you will at least have the flap to secure the door. I have a 3-Dog stove and is plenty warm for that size tent. I would probably go with a lighter canvas weight next time and with shorter walls - I have 5 ft. walls. The tent we use for sleeping is the same size but lighter wt. canvas (sunforger), 4 ft. walls. and smoke hole in the wall - I like it a lot. As I get older (47) it's getting a little harder to move the heavy canvas tent around, even just rolling it up and putting it into it's bag. When I first purchased the tent I too drove to the site, in the last few years we've been hauling it in from 40 yds to over 1 mile (with a lawn cart). The light wt. tent is easier to use with pole found on site and just tieing it up to surrounding trees. And looking to the future I might get the lighter wt. setup. When I first set up my tent, my self made frame wasn't quite the right size, too long, and I tore a 10 inch hole in a corner, but I used the repair kit that came with it and haven't had a problem since. I have had one grommet go out.
I would not do without the floor, stove, rain fly, smoke hole in wall, and what I would get in the future would be some type of oven for either on top of the stove, or in-line with the chimney.
Lots of stuff to research - good luck.
