I've had one of these for 20 years. I used it on a regular basis for about 15 years. I now have a VW westfailia camper. It's a shame because the pop up just sits in the back yard. I have the largest one they made. Yes, they did come in sizes. Mine is 10 ft. long with a 4 ft. pushout on each end. That makes it 18ft. long when it's opened up. It has 4 beds, enough to sleep 8 people if need be. A sink, a refer, stove, a good sized heater, 12 volt inverter,and 2 tables and an awning in front. It also has 2 propane bottles up front.The side windows are the full length of the body and slide to open. They are plexiglass.This was definitley the cadillac of pop ups in it's day. I would consider selling mine to someone on the right coast for a very reasonable price. One thing to look at if someone is buying one other than mine is the 2 transmissions that raise and lower the top. As far as I know they are not replacible. When I replaced mine the guy told me they were the last ones on the planet. Hope this helps
