I would add a window or two for ventilation, they can get pretty warm even during the winter. I'm not sold on floors in wall tents, I use tarps, they are easier to clean that way. Make sure it has storm flaps at the door. If you have a zipper on the door make sure you have some way to secure the door if the zipper fails. I had the maker add four straps and fastex buckles on my storm flaps inside and out. Add a strap and buckle at the corners of the door wall so you have some way to hold your door open. I also like two doors that way if a bear comes in one you can run out the other. I use a Cylinder stove Outfitter model, it works great but is quite heavy for packing. I make my own frames using 1/2" electrical conduit for the walls and 1 3/8" material for the ridge. They are easy to make and cost around $125. If you're interested in how I make my frames give me a call 801-550-4973.
