Man I used the 12x12 Alaknak on one trip to Texas hunting javelina.( 1 week) And that thing leaked like a sieve. I mean 3” of water on the floor. Luckily we slept on bunk beds and were up out of the water. The roof flap opens “ down hill”, instead of like a shingle, which would help. But we couldn’t keep the flap up and the wind kept blowing it open, and water ran in like a facet. The plastic windows are in the roof, that plastic gets brittle when cold, and will only get worse with age. It was the only time that tent was used, Cabela’s sent me a return tag, which I did for a refund. My brother has the larger model ( with the flap the right direction, and widows in the walls vs roof) and he didn’t have any issues, but never had it in a heavy rain either. Your question about the stove and cover. Never used a stove in it.
