Fifth Wheel RV Maintenance

Introduction

With the complexity of the modern RV comes a need for a fair amount of maintenance to keep it running smoothly and safely. Below you will find my personal Fifth Wheel RV Maintenance list. No RVers list will be the same as there are many variables that go into what needs done and when. My list is based on owning a fifth wheel trailer and using it pretty much full-time. Many things can influence how often things need to be checked. So having said that here is what works for me.

Under Carriage maintenance

Wheels and Undercarriage

  • Brakes – every 6 months to one year pull the wheels and clean and inspect the brake pads and drums. Replace parts if worn.

  • Make sure the electric brake wiring is in good shape and not rubbing on anything.

  • Wheel Bearings – every year or 12,000 miles clean, inspect, repack the bearings and install new seals.

  • Inspect tires and rims for any cracks or defects before any trip.

  • Have a look at the suspension and axles before every trip and every few months check for correct torque settings on nuts and bolts.

  • Before every trip check torque setting on wheel lug nuts.

  • Before every trip check for proper tire inflation.

    Great article…what are some of the lubricates that you use…WD40? Or some other?

    Thanks Bob, I generally like to use a lubricant that doesn’t leave behind a film if it’s something on the outside the rig. Like a dry lithium grease so it doesn’t attract dirt and dust. Anything they use for boats is usually great for the RV. Some places like the wheel bearings need a special bearing grease. There is also a spray on dry lube designed for the slide rails that works great for the stabilizer jacks as well.
