Preventative Maintenance Tips for RV Campers

July 8, 2024

Owning an RV camper is an incredible way to explore the great outdoors, enjoy spontaneous adventures, and live a life of freedom. However, maintaining your RV in top shape is crucial to ensuring it remains reliable, safe, and ready for the road. Preventative maintenance can save you time, money, and a lot of headaches down the line. In this post, we’ll cover comprehensive preventative maintenance tips to keep your RV camper in excellent condition.

1. Regularly Inspect the Roof:

Check for Leaks and Damage: The roof of your RV is one of its most critical components. Regularly inspecting it for leaks, cracks, or any signs of damage can prevent significant water damage inside your RV. Look for any areas where the sealant may be wearing off or where the roof material is damaged.

Apply Roof Sealant: If you notice any potential leak points, applying a high-quality RV roof sealant can prevent water from seeping in. Be sure to follow the manufacturer’s instructions for the best results. It’s advisable to do this inspection and maintenance at least twice a year, particularly before and after the rainy season.

2. Maintain the Tires:

Check Tire Pressure: Maintaining proper tire pressure is essential for the safety and efficiency of your RV. Underinflated tires can lead to poor fuel efficiency and increased wear, while overinflated tires can be more susceptible to blowouts. Check the tire pressure before each trip and ensure it matches the recommended PSI listed in your RV’s manual.

Inspect for Wear and Tear: Regularly inspect your tires for any signs of wear, cracks, or bulges. Uneven wear can indicate alignment issues or improper inflation. If you notice any irregularities, it’s best to have a professional inspect and possibly rotate the tires.

3. Monitor the Battery:

Check Battery Levels: The battery is crucial for powering your RV’s electrical systems. Regularly check the battery’s water level (if applicable) and ensure it’s fully charged. Keeping your battery properly charged extends its lifespan and ensures you have power when you need it.

Clean Battery Terminals: Corrosion on battery terminals can lead to poor electrical connections and reduced battery life. Clean the terminals periodically with a mixture of baking soda and water, and apply a terminal protector to prevent future corrosion.

4. Service the RV’s Engine:

Regular Oil Changes: Just like any vehicle, your RV’s engine requires regular oil changes to run smoothly. Refer to your owner’s manual for the recommended oil change intervals and stick to them diligently. Regular oil changes keep your engine lubricated and prevent premature wear.

Inspect Belts and Hoses: Belts and hoses are critical for the engine’s performance. Inspect them regularly for any signs of cracking, fraying, or leaks. Replacing worn belts and hoses before they fail can prevent breakdowns and costly repairs on the road.

5. Maintain the Brakes:

Check Brake Pads and Rotors: The brakes are vital for your safety. Regularly inspect the brake pads and rotors for wear and tear. If you notice any unusual sounds or a decrease in braking efficiency, it’s time to replace the brake pads or rotors.

Flush Brake Fluid: Brake fluid can become contaminated over time, leading to reduced braking performance. Flushing the brake fluid every couple of years ensures your brakes operate at their best.

6. Inspect the Plumbing System:

Check for Leaks: Water leaks can cause significant damage to your RV’s interior. Regularly inspect all plumbing connections, hoses, and fixtures for leaks. Tighten any loose connections and replace any damaged hoses or fittings.

Sanitize the Water System: Sanitizing your RV’s water system prevents bacterial growth and ensures safe drinking water. At least once a year, flush the system with a mixture of bleach and water, then rinse thoroughly.

7. Maintain the HVAC System:

Clean and Replace Filters: The HVAC system keeps your RV comfortable in all weather conditions. Regularly clean and replace the filters to ensure efficient operation and good air quality inside your RV.

Inspect the Air Conditioning Unit: Inspect the air conditioning unit for any signs of damage or wear. Clean the coils and fins to maintain optimal performance. If the unit isn’t cooling effectively, consider having a professional inspect it.

8. Keep the Exterior in Good Shape:

Wash and Wax: Regularly washing and waxing your RV’s exterior not only keeps it looking good but also protects the paint and body from the elements. Use a mild detergent and a soft brush to clean the exterior, and apply a high-quality RV wax to protect it from UV rays and road grime.

Check Seals and Caulking: Inspect all seals and caulking around windows, doors, and seams for cracks or deterioration. Reseal or re-caulk any areas that show signs of wear to prevent water intrusion.

9. Service the Generator:

Change the Oil: Regular oil changes are crucial for the generator’s longevity. Follow the manufacturer’s recommendations for oil change intervals. Regular maintenance ensures your generator is ready to provide power when you need it.

Inspect and Replace Air Filters: Dirty air filters can reduce the generator’s efficiency and cause it to overheat. Inspect and replace the air filters regularly to keep your generator running smoothly.

10. Maintain the Propane System:

Check for Leaks:  Propane leaks can be dangerous. Regularly inspect the propane system for any signs of leaks. Use a propane leak detector solution or a mixture of soap and water to check connections and hoses. If you notice bubbles, you likely have a leak that needs immediate attention.

Inspect and Replace Regulators: The propane regulator ensures a steady flow of gas to your appliances. Inspect the regulator for any signs of wear or damage and replace it if necessary.

11. Ensure Proper Storage:

Prepare for Off-Season Storage: If you’re storing your RV for an extended period, proper preparation is essential. Drain all water tanks and lines to prevent freezing and damage. Remove perishable items and thoroughly clean the interior to prevent mold and pests.

Use RV Covers: Using a high-quality RV cover protects your vehicle from the elements, including UV rays, rain, and snow. Ensure the cover fits properly and is secured to prevent wind damage.

12. Regularly Test Safety Equipment:

Check Smoke and Carbon Monoxide Detectors: Smoke and carbon monoxide detectors are crucial for your safety. Regularly test these detectors and replace the batteries at least once a year. Replace any detectors that are more than 10 years old.

Inspect Fire Extinguishers: Ensure your RV is equipped with a working fire extinguisher. Regularly check the pressure gauge and inspect for any signs of damage. Replace the extinguisher if it’s past its expiration date.


Preventative maintenance is crucial for keeping your RV camper in optimal condition and ensuring a safe and enjoyable travel experience. Regular inspections and upkeep of the roof, tires, battery, engine, brakes, plumbing, HVAC system, exterior, generator, and propane system can prevent costly repairs and extend the lifespan of your RV. Remember to also properly prepare your RV for off-season storage and regularly test safety equipment like smoke detectors and fire extinguishers.
