We have a Jayco pop-up camper for sale. Figured someone might want it for PorcFest. It supposedly sleeps six, but I think that's pushing it, unless some of them are small children.
It's about 12 feet, closed, about 24 feet, open. Has a sink and a propane cooktop.
Mid-'80's, but well-maintained.
Uses a 1-78" ball, and I have one available if you don't. It's light enough to tow with a large car (eg, Crown Vic, or the like), or pretty much any truck.
Reasonable delivery within NH possible.
