What did you do to your Class C MH today???

Took my new to me RV I bought used in January in for it's first oil change (with me) today and to have my buddies at Ford go through the E450 engine and chassis from one end to the other. They confirmed that everything is still like brand new (it's a 2006) and there is absolutely nothing it needs. Not even filters as it looks like they were all changed recently. They checked it in the Ford database and it's never had any warranty work done and there are no recalls. Yea! I'm a happy camper. All I'm waiting for now is my new free set of Michelin tires to come in.
