Chassis Maintenance

Regular chassis maintenance is imperative to keeping your coach safe and reliable for years to come. We recommend that you proactively schedule and record service at optimum intervals and have routine maintenance performed at a Freightliner location.

To use the maintenance sheets below to their full advantage, you’ll want to download the complete RV chassis maintenance manual first. The page number in the “MOP” column on the far right of each maintenance sheet will direct you to the full explanation of required inspection or service in the chassis maintenance manual.

As always, if you have any questions about your vehicle’s maintenance needs, give us a call at 800.FTL.HELP.
