We had a bare-bones 10ft Jayco pop-up that we put up on CL a few years back. We had 3 people call on it within 24 hrs. It had no heat, no AC, no fridge, no slide-out and the faucet on the sink was broken. I didn’t think we would even get $1000 out of it and ended up selling it for $1300.
Then we had a 12ft Rockwood pop-up that had everything. Heat, AC, a slide-out, an add-a-room, removable stove, extra storage trunk on the front and everything worked. It took us almost a year to sell it and we dropped the price at least 4 times.
So it’s really hit-or-miss.
