the seller says this:

The generator has 1628 hrs.
The milage is 173,000 it has 135,000 when we bought it in 2013.
The jacks on the right side are not retracting correctly, probably a solenoid.
The alternator on the engine is oil cooled and seeps a little oil, it has done this since we purchased it. It has no other engine leaks.
The auto door locks are air powered and they do not all lock with the button, but each one can be locked with a key.
Will need new tires in the back, they look great with no cracks but they are 10 years old.
The the step works most of the time, I think it has a mercury switch that may be the problem.
If I think of anything else I will let you know.
The new Aqua Hot is $12,000 it will heat the coach, storage bays, engine and water. Aqua Hot is one of the best features.
