Well, thats's newer then my Ford E-450 base motor home. :)
But CRC has a point about tires. In my case the suggestion is to replace the tires before they're used more than 5 years no matter how few miles were put on them. The sun and oxygen in the air age them. Some people cover the tires when they are parked to extend their life.

"There is a cult of ignorance in the United States, and there has always been. The strain of anti-intellectualism has been a constant thread winding its way through our political and cultural life, nurtured by the false notion that democracy means that "my ignorance is just as good as your knowledge."
-- Isaac Asimov
