We had a zip-in screen room, with privacy flaps, for our 1996 pop-up. (I can only hope they have improved things since the mid-90's!) While we loved having it AFTER it was up, it was nothing but a pain to set up and take down. It really did double our "living" space. We never even used the stove inside the camper. It always went in the screen room, as did coolers, a table, etc.
