Looking at a 1992 popup truck camper but can on find any spec or info on the net. Nada does not go back that far. Thanks in advance for any help finding info
Putting a value on a camper that old is tough. Most campers that age are not in like-new condition, and have had leaking issues at some point, if they aren't leaking right now.
Could be worth anywhere from $50 to $750, IMHO.
Basically, if you feel uncomfortable paying what the seller is asking, then pass on it.
