I can only speak from what is said around the "coffee table" at work with the guys. They all swear by thier Davis tents. I will be purchasing a single pole 12x12 canvas tent for my pack in trips this fall. Up until this year I have used a Cablea's outfitter tent but will be switching to a canvas tent. When we talked about it they were all 100% in agreement Davis is the only tent out there. One of the guys have a 20x30... we call the "circus tent" made by Davis. They have a scratch and dent sale every spring that the tents are about 50% off. Many of these are damaged at all just were a screw up with an orderor have a stained spot on them. I would call them and talk with them.
