I have a travel trailer that I have camped in for the past 7 years. I know zip about popups. However, I just came across a 1997 Coleman Sun Ridge that is mint. The owner wants $2500. NADA book is $150...
Check the roof carefully. Coleman campers were not BUILT by Coleman and there were a number of years where roofs were very problematic (cracking, sagging and leaking). Coleman and their builder ended up parting company over the issue. Also since it was mentioned, the front truck models also had a LOT leaking issue in that front storage compartment.
