It boils down to how you are going to get your equipment to it's destination, how comfortable you want to be when you get there, what you require to be comfortable, and what your budget will afford.
And that is how I arrived at the Fred Meyers tent. It is what I had, could not afford to get anything new, let alone upscale.
I had the budget of weight too. I had a 4 to 8 dog team on various years and although each dog can pull 160 pounds all day on snow, with 4 dogs that equals 640 pounds and with 8 dogs = 1,280 pounds. Although they CAN pull that amount with lots of conditioning training, I tried to put as little on them as possible as we were going 100 miles in 3 days and although the easiest day is 25 miles, the shorter toughest day is almost straight up and down. With me, my sled (which is 35 pounds) and gear, I tried to keep it around or under 350 pounds, including food, water, camping gear. And I have picked up stranded people in the mountains with my team before, so I have that ability as I have that spare weight allowance by keeping it at a minimum to begin with.
Depending on what you have to Bug Out in, weight is everything.. I know I would not want to carry my sleeping bags with me on my back in a BO situation. They are pretty heavy. But I would rather take them over than a more stout tent than I had if weight came back to the issue, the sleeping bags would win. When it snows (and it was a very dry snow that time of the year when I did this), I wake up periodically and thump the tent to get the snow to drift off it, JUST in case it might cave in. It never seemed to be threatened by caving.
Some years we had straw dropped in for insulating the bottoms of our tents, some years we had to use pine boughs. Realistically, at those temps I was in, I am not sure it really made a difference? I know some floors are insulated in some tents.
I know two years ago when I was on the road every two weeks for 5 months and living out of my truck, my tent and mom's couch when I was house hunting between Oregon and Canada, and it was coming November and I was in the middle of the mountains anyway so in the summer it could hit freezing marks. EASE of putting it up when you are cold and tired is a DEFINATE PLUS!!! I was down to 5 minutes for putting my tent up (a new Fred Meyers tent by now as the zipper finally went out of the other one after 20 years -darn it, plus a 130 pound dog, so I upgraded to a 3 person tent, which is really a 1 dog, gear and 1 pregnant chick tent). When you are on the road and putting up and tearing down a tent 6 times a week, you want it to be fast and easy.
