I purchased one from Cabelas about 4 years ago. The best investment I ever made! I've used mine at 10500ft in Colorado with a rain storm that I thought we were going to blow away, no issues whatsoever. Have had the snow piled on top and once again, no issues. Have run a wood stove and propane heat and prefer the propane. I do not think you will be disappointed.
I have the 12x12 and it will sleep 2-men, cots and all their gear very comfortably. 3-Men on cots is OK as well. 4-men on cots is a little crowded but we have done it before. Any questions, feel free to PM me.
