I was looking also a couple of weeks ago. Using the internet searching, wall tent, I found quite a few tent companies that make canvas wall tents. I would like one that is about 6 x 8' with a stove flap.
Last week I was stranded for five days out on Prince William Sound and sure could of used a good wall tent. The problems with then is: weight, mold and poles. But, if your doing a week long hunt in Idaho or Oregon they should be the nuts when the snow hits.
Let me know if you find a good one. Oh, you might try Alaska tent Corporation.
