Nothing ruins a vacation faster than a preventable RV breakdown. Before embarking on a long trip, a proper inspection and tune-up can mean the difference between smooth travel and being stranded on the side of the road.

Here’s how to prep your RV for a big journey.

1. Test All Appliances

A/C, furnace, fridge, water heater, microwave—turn them on and confirm they operate properly.

2. Inspect Your Roof & Seals

Even a small crack can become a huge leak in stormy or humid conditions.

3. Check Tires & Date Codes

RV tires often age out before they wear out.
Check:

  • Tread

  • Cracks

  • Sidewalls

  • DOT date code (replace around 5–7 years)

4. Verify Battery Health

Weak batteries = slide issues, furnace problems, lighting failures.

5. Sanitize the Fresh Water System

Traveling with a clean system prevents illness on the road.

6. Confirm Slide-Out Operation

Binding, slow movement, or popping sounds mean you need service ASAP.

7. Test All Lights & Signals

Safety first—especially when towing.

8. Check Brakes & Brake Controller

If towing, inspect trailer brakes and ensure the controller is properly calibrated.

9. Run the Generator Under Load

Make sure it can operate your A/C or appliances before you need it.

10. Get a Professional Pre-Trip Inspection

A mobile technician can spot issues that RV owners might miss.
