Recently bought a used 1999 motor home with a Ford V-10 gas engine. The owners manual is very generic in nature and does not address the f-53 chassis.

I contacted Ford regarding the maintenance schedule and got a "ain't my problem" form letter, telling me to contact the RV dealer. Guess what the RV dealer had already told me to contact Ford .

My question is: how often should I change the oil, lube, filters, transmission, etc.

Any help appreciated. I did not think that a thing as simple as a maintenance schedule would be such a problem..
