Mark is a retired US Army Maintenance Chief Warrant Officer Three. He knows what is required to keep large fleets of combat vehicles prepared for the rigors of war. The same thing required to get many years of reliable service and use from your RV. Preventive Maintenance is the cornerstone for maintaining your RV in peak running and operating condition. Preventive Maintenance is maintenance that you the owner can perform on your RV before a problem exists. This guide, with 30 pages of preventive maintenance checks, is designed to prevent or identify potential problems that could lead to mechanical breakdown, or failure of a component or system on your RV. Preventive Maintenance consists of cleaning, inspecting, lubricating, adjusting and servicing your RV. Preventive Maintenance does not supersede the scheduled maintenance recommended by the chassis and RV manufacturer and it is imperative that those schedules are followed. Some of the scheduled maintenance for your RV must be performed by an RV dealer, chassis manufacturer or authorized service center.
