The Ultimate RV Maintenance Checklist: Keep Your Rig Road-Ready All Year

When it comes to RV ownership, one truth never changes: a little maintenance goes a long way. Whether you’re a weekend warrior or a full-timer chasing sunsets, keeping your rig in peak condition means fewer breakdowns, more comfort, and a safer trip for you and your crew.

This ultimate RV maintenance checklist will help you stay ahead of costly repairs while ensuring your RV systems — from awnings to toilets to refrigerators to air conditioners — work exactly when you need them.

1. Exterior & Awnings: Protect Your RV’s First Line of Defense

Your RV’s exterior shields you from the elements, so regular inspection is critical.

• Wash and wax the exterior to protect against UV rays and road grime.

• Inspect roof seals and seams for cracks or leaks.

• Check your RV awning fabric and hardware. Over time, awnings can crack, mildew, or lose tension, leaving you without shade or protection during a trip.

2. Plumbing & Sanitation: Avoid the Headaches

Few things can ruin an adventure faster than plumbing issues. Stay ahead with regular checks:

• Inspect toilet seals for cracks or leaks.

• Check water lines and fittings for drips and tighten connections.

• Flush your black tank properly and treat it with chemicals to prevent odors.

• Replace worn toilet parts (water valves, seats, gaskets) before they fail mid-trip.

3. Refrigeration: Keep Food Cold on the Road

A properly working refrigerator is critical for long trips. Without it, spoiled food and warm drinks can turn a vacation into a headache.

• Clean exterior vents and make sure there’s no dust or debris blocking airflow.

• Inspect the cooling unit for signs of leaks or corrosion.

• Check door seals — a worn gasket can cause cooling loss and wasted propane/electricity.

• Keep your RV level — especially with absorption-style fridges like Norcold and Dometic, as they need gravity to circulate coolant properly.

4. Climate Control: Stay Cool in Summer, Warm in Winter

Your RV’s air conditioner is one of its most used appliances, and it needs regular upkeep:

• Clean or replace AC filters every few weeks of use.

• Inspect shrouds for cracks and damage.

• Check AC control boards and capacitors if your system isn’t cooling efficiently.

• Run your furnace and heat strips before cold weather arrives to make sure they’re ready.

5. Electrical System: Power Up Without Problems

• Test your converter and inverter to ensure steady voltage.

• Carry a surge protector to prevent campground power spikes from frying your system.

• Inspect battery connections and keep terminals clean.

• Consider a multimeter test to confirm charging levels.

6. Tires & Brakes: Safety on the Road

• Check tire pressure before every trip.

• Look for cracks or uneven wear on sidewalls.

• Grease your wheel bearings at recommended intervals.

• Inspect brake pads, rotors, and lines before hitting steep grades.

7. Interior Systems: Comfort Matters

• Test smoke detectors and replace batteries.

• Lubricate hinges, slides, and locks.

• Deep-clean vents, flooring, and upholstery.

• Open and close windows, skylights, and slide seals to prevent sticking.

8. Seasonal Prep: Be Ready for Anything

• Winterize plumbing by blowing out lines or adding RV antifreeze.

• In spring, de-winterize with a flush and sanitization of the freshwater system.

• Before summer, check your AC unit, fridge ventilation, and awnings.

• Before fall, inspect your roof and seals for weatherproofing.
