I think there is a scam, do they want a registered check etc.? I would call the police in the town it is located and see if they know the owner. Craigslist has lots of these scams, there is no doubt it is scam but follow up, could be an old guy who just wants to dump it. You want a Mechanic check over the engine, an RV tech check over the interior working systems(make sure all systems work) but my gut tells me it is a big fat SCAM!!! Be careful!!!
All the pictures are from a new coach and not the real coach from what I could tell which is a big problem and clue it is scam,if they have money for the MH then they have a damn camera!
