I will second the Cabelas tents. I own the I.S.Q. Version they no longer make. Similar to the Alaknak wall tents. I would stand by them any day. I have owned mine three years and used it every elk season here in Idaho. Never had mine up in snow as my elk season is September during archery. I have a wood stove and it really does well for space, water shedding, warm, easy relatively to set up with one guy, or with help. The most I have slept so far is four with two dogs, and it wasn't even close to full, but that is because of the i.s.q. pods. The build and material is nearly identical to the Alaknak so I feel safe to say they are good tents too.
as far as the big horn.... I see so many returned in the bargain cave its not funny. They have a weird shape, and as soon as you start a fire in your wood stove, it typically melts the side wall right there. Every returned big horn I have seen has the same issue. Its really blows my mind that Cabelas still sells them. Or why cant they redesign the fire wall to be more boxed to avoid that?
