Well I'm probably the only person that brings a 20x10 Vendor Tent with them while camping, but I tell you the extra 200 s.f of space is nice... now if I could just figure out a way to screen-in half of it....
very cool.
the screen can be ordered. the pop-up gazebos at Retail stores come both ways... with and without screen. they may order one for you if it's not a stocked item. also the manufacturer may sell you a set. www.bondmfg.com
