My concern is things like the shredded slide toppers may be an indication of other overall neglect, if they could not be bothered to maintain the slide toppers, did they perform chassis maintenance, do oil changes, how about annual inspection / replacement of the anode rod in the water heater (if it has one), was the plumbing system properly winterized each year, if repairs were done were they done right, or were they bandaid fixes, ... Too me this coach would probably be a hard pass, instead I would look for a coach that showed signs that the previous owner cared for and maintained it, this may be little things like aftermarket bug screens on the appliance vent covers, rain guards added to the roof vents, any signs of aftermarket upgrades of any type, sure service records would be great too, but any sign that the owner paid attention to maintaining the coach would be a BIG plus. At the end of the day the issue is not the obvious issues, but it is what you can't easily see.
