Maintaining a car towed by an RV, often referred to as “dinghy towing” or “flat towing,” requires specific attention beyond regular car maintenance. Overlooking these crucial steps can lead to costly repairs and stressful situations on the road. This guide dives deep into the essential maintenance procedures for a car towed by an RV, ensuring a smooth and trouble-free journey.
Understanding the Unique Demands of Dinghy Towing
Towing a car behind an RV puts unique stresses on the vehicle. Unlike regular driving, the towed car’s transmission, wheels, and tires rotate constantly without engine power. This continuous motion generates heat and friction, demanding specialized lubrication and careful monitoring. Furthermore, exposure to varying weather conditions and road debris necessitates regular inspections and preventative measures.

Essential Maintenance for a Car Towed by RV
Transmission Care is Key
The transmission is arguably the most critical component to maintain in a towed vehicle. Since the engine isn’t running, the transmission doesn’t receive the usual lubrication. This can lead to overheating and significant damage. Consult your car’s owner’s manual for the manufacturer’s recommended procedure for towing, which may involve using a transmission lubricant additive or running the engine periodically during long tows.
Tire and Wheel Maintenance
Tires on towed vehicles wear differently than those on actively driven cars. Rotating your tires regularly and maintaining proper inflation is vital. Uneven wear can occur due to the constant rolling without engine power. Consider investing in high-quality tires designed for extended towing. Wheel bearings should also be inspected and repacked regularly.

What should I check before each tow? Before each trip, check tire pressure, lights, and tow bar connections. Ensure your battery disconnect is working properly to prevent battery drain.
Braking Systems and Supplemental Braking
Many states require supplemental braking systems for towed vehicles exceeding a certain weight. These systems provide additional stopping power and reduce strain on the RV’s brakes. Regular inspection and maintenance of the supplemental braking system, including brake fluid levels and actuator functionality, are essential for safety and performance.
Lighting and Electrical Connections
Ensure all lights on the towed vehicle function correctly, including brake lights, turn signals, and running lights. Verify the wiring harness connection between the RV and the towed car is secure and free from corrosion. This will prevent electrical issues and ensure visibility on the road.

Regular Fluid Checks
Just like a regularly driven car, your towed vehicle requires regular fluid checks. Check engine oil, coolant, brake fluid, and power steering fluid levels before each trip and at recommended intervals. This will ensure the car remains in good working order when you decide to drive it independently.
Why is battery disconnect important? A battery disconnect prevents your towed car’s battery from draining while being towed, ensuring it starts when you reach your destination.
Protecting Your Investment: Preventative Maintenance
Beyond the specific requirements of dinghy towing, adhere to the regular maintenance schedule outlined in your car’s owner’s manual. This includes oil changes, filter replacements, and other routine services. Remember, preventative maintenance is always less expensive than major repairs down the line.
“Regular maintenance is your best insurance against unexpected breakdowns and costly repairs,” says John Smith, a certified automotive technician with over 20 years of experience in RV and towed vehicle maintenance. “Don’t neglect the small things, they can often prevent big problems.”
Car Towed by RV Maintenance Schedule
Creating a comprehensive maintenance schedule tailored to your specific vehicle and towing habits is crucial. Here’s a sample schedule to get you started:
- Before Each Trip: Check tire pressure, lights, tow bar connections, battery disconnect, and fluid levels.
- Every 5,000 Miles: Check and lubricate the chassis, inspect the supplemental braking system, and rotate tires.
- Every 10,000 Miles: Change engine oil and filter, inspect and repack wheel bearings.
- Annually: Inspect and service the transmission, check and flush brake fluid, and inspect all wiring connections.
“Remember to consult your owner’s manual for specific maintenance recommendations for both your RV and your towed vehicle,” advises Jane Doe, a seasoned RVer and author of “The Ultimate Guide to RVing.” “Every vehicle is different, and following the manufacturer’s guidelines is key to ensuring optimal performance and longevity.”
