Frank, I have a 12x12 Pyramid tent from Panther Primitive, can be set up a couple different ways. Single pole inside , 2 poles over outside or a rope over a tree limb. I have always used the int. single pole just under 9' in center. I have Bobcat trapped out of this tent in some pretty rough weather 10 degree nights,I have a 2 dog stove and will run ya out with heat,We put down a pc. of rubber roofing for a floor and use cots, gear goes under cots, drilled center pole for some 60D nails to hang clothes and lantern on. Made a real nice toasty camp for a week and caught a cat to boot. I can set this up in 5min by myself, easiest tent for setup that I have ever owned. Some great ideas on this thread, need to try a fan in the top of the pyramid, and shower tub sounds real good. Bob
