I have the Doghouse also. It fits two office chairs and my Canadian Tire folding metal saw horse that I use as a gun rest right under one of the windows. As mentioned they are water resistant not water proof, so I seam sealed all the seams and that really helped, only a little bit of water drizzles down the walls from the zippers if it rains real hard, but never touches me,
Watch the video on how to fold it back up, or you will go nuts trying to put it away following the instructions that came with it. Its really easy to set up and take down, literally a couple minutes and its done.
Its amazing how much warmth the tent holds, and being able to get out of the wind means you can stay out longer on those cold days.
I am not sure how much snow the tent could hold, but last year it snowed a few inches and it help up nice, but I learned that you should knock the snow off before you go in because once your body heats warms the inside, the snow starts to slide off, and it makes a bit of noise.
I like to buy from local suppliers, but once again I seen the tent here for $100+ and I believe I paid $45 at Natchez.
