That's a new one for me. You need to look at the whole coach and to see if everything works. Have a mechanic look at the drivetrain, look at the date codes on the tires, not the tread but the actual codes. If you know nothing about coaches hire a mobile mechanic to inspect it for you, that is the best money you will ever spend. Remember, the seller knows little to nothing other than he wants your coin. Maybe the owner was a short trip taker or sat for a month in one spot. Many purchase coaches then find it's not for them or illness scales them back. With that said ,who cares what the owner did before you, what is the items condition.
