Clam screen roomThey aren't cheap or compact - but I carry a "Clam" screen room for Ed and I and the dogs to loll around in. Ours is 5-sided; probably 7' across and almost 7' tall. There are additional wall panels you can purchase for either privacy or protection from the elements. Takes about 45 seconds to set up - the walls just pop into place. And if a big windstorm comes up, the walls "un-pop" and it flattens itself out without damage. I first discovered these at a teardrop-camper rally - they sort of offer the "living room" that most teardrops (and van campers) are lacking
