If you find one that is a distance away you could consider contacting someone on rv.net/tc forum that lives in the town or nearby where the camper is located.
I did that for someone that lived in Texas and found a lance and truck here in Sacramento.
He PM'ed me so I went to see the camper and truck.
I took pictures for him and told him my thoughts. The Passenger side (right) front jack had, at one time, been torn off the camper.... ugly repair and did not look like it was solid... That and water stains in over head cabinets (roof seams leaking). As for the truck well that is a long story too... Needless to say it was not a good deal for him.
So you might give that a try.
