Newbie, thinking about buying a 2004 sportscoach cross country 376DS SE. I am wanting to know about the mileage on RVs. This is a diesel pusher, I believe, I think it has 60,000 miles on it. Is this too many miles on a 2004 rv or considering it is a diesel, is it still good to go. The coach is on a lot in Ft. Pierce, FL and I live in West Virginia, saw it on the internet, put up a deposit to buy, but I will have to go look at the coach before I buy.
