Our 2004 has been excellent as far as what Monaco put on it. Workhorse chassis had some problems but your's is a Ford so I don't know about the chassis.
My slides are both electric gear driven. Snapped a gear tooth on the bedroom slide, replaced gear and it was fine.
If something happened to this coach I'd go try to find a used one just like it.
How much are they asking for it and how old are the tires?
