Does anyone make a poleless tent, that's not one of those contraptions that has inflatable tubes to hold it up? I'm thinking of something with a lenth of about 8 feet, about 3 feet wide and 1 1/2 feet tall. It would be long enough to put an assault pack at your head or feet to keep it dry, enough space to roll over, and that's about it. It would be staked at the 4 corners, and be supported by 550 cord or the like strung between trees, or other field expedient methods. If such a thing existed would any of you guys buy it? Or do you already have one, and I've just never heard of it?
