Pam,
as previous stated, I am very good friends with the owner. We just got back from California 2 weeks ago and his coach ran like a champ. His 60 series ran just like mine. Im not sure if he told you, but this coach was previously owned by Ganassi racing. Generally race coaches have there own drivers who pamper them. My coach was previously owned by Dale Earnrhardt Jr. and his driver kept the coach up very well. There was a compartment full of filters and other odds and ends to maintain the coach. I personally would not worry about the mileage at all.
and Richard, the OU stuff just adds value to the coach
