I just bought a 15x15 this past spring from Beckle tents down in E.Portland. Spent memorial day weekend building the frame for it. Had my cousin build my firebox. Used it twice since than and love it. it would make a real cool steelhead camp when the rivers are right. the flooring we put a grey tarp down than some of the indoor outdoor carpet from homecheapo than put the rubber back floor matts from Cintas or whatever down along your bed / cot. built the frame to have a 5' overhang for dry cooking and firewood storage on the porch. I have a 20x24 grey tarp that goes over the top of the whole tent that works great.Good luck,

PS, I'm into the set up about $1,500.00 is all.
