One example: Our 2004 rig has not been driven much since 2005 due to health, family, aging problems and other issues. We also lived in it during an extensive home remodel.Has around 10K miles on it. I had to replace the roof AC unit, fridge, converter charger, house batteries and fresh water pump at about the 10 year point. Roof has been maintained, no leaks. It starts and runs fine and has new Michelin tires from the last recall. We don't plan to sell it, but if we ever do, somebody will get a nice sun-faded rig with very low miles. I expect there are a number of owners that have had unexpected setbacks in RV usage. You might look for parked RV's in driveways and ask owners if they would consider selling. Just sayin, not all low mileage rigs are junk.
