Your trusted guide to a smooth, stress-free road trip season
Summer is the season for hitting the road, but if your RV isn’t properly prepped, you could find yourself stuck with unexpected repairs instead of enjoying the open highway. As a mobile RV repair technician based in Fullerton, CA, I’ve seen firsthand how a little preparation goes a long way in preventing costly breakdowns.
Here’s a complete, step-by-step checklist to help you get your RV summer-ready in Orange County (or anywhere the road takes you).
1. Test Your Rooftop RV Air Conditioner
Stay cool before the heat hits
Orange County summers can get hot — and a failing air conditioner can turn your trip into a sweaty mess. Before you roll out:
- Turn on your rooftop AC and test for strong airflow
- Listen for unusual noises (rattling, humming, etc.)
- Check if it’s cooling quickly and evenly
- Clean or replace filters
- Schedule a professional RV AC tune-up if you haven’t in the past year
Tip: A rooftop AC service includes coil cleaning, capacitor testing, and full performance checks. Murphy Mobile RV Repair offers this on-site.
2. Inspect Your Tires (Don’t Just Glance at Them)
Blowouts are more common than you think
Hot pavement and worn tires don’t mix well. Check:
- Tire pressure (including your spare)
- Tread depth
- Sidewall cracking or dry rot
- Tighten lug nuts and torque to spec
- Look for uneven wear, which could signal alignment issues
Pro Tip: RV tires can “age out” before they wear out. If they’re over 5–6 years old, get them professionally inspected or replaced.
3. Test Your Battery & Electrical Systems
No one wants to lose power halfway through a trip
Summer heat can shorten battery life, especially if your rig sits idle. Before your trip:
- Fully charge and test your house and chassis batteries
- Check terminals for corrosion
- Inspect wiring for loose connections
- Test lights, outlets, and appliances
- Ensure your inverter and converter are functioning
If you’re experiencing flickering, dim lighting, or a battery that won’t hold charge, it might be time for a mobile electrical diagnostic.
4. Flush and Sanitize Your Water System
Especially important after storage or winterization
Even if you don’t drink from your fresh tank, you don’t want stale water running through your pipes.
- Drain, flush, and sanitize the freshwater tank
- Check for leaks under sinks and around fittings
- Test the water pump pressure
- Inspect your water heater and pressure relief valve
- Check for any musty odors or sediment buildup
Note: Murphy Mobile RV Repair can inspect and flush your water heater if unsure.
5. Give Your Roof and Seals a Close Inspection
Summer sun can do serious damage over time
Climb up and look closely at:
- Roof seams and sealant (check for cracking or separation)
- Vent covers, skylights, and AC shrouds
- Any signs of pooling water or soft spots
- Seals around windows and doors
Catch it early: Small cracks lead to major leaks. We offer on-site roof inspections and resealing to help prevent future water damage.
6. Stock Your Tools and Emergency Gear
Prepare for the small stuff, so the big stuff stays small
Every RV should carry:
- Tire pressure gauge and torque wrench
- Fuses and spare bulbs
- Sewer hose and water pressure regulator
- Jumper cables
- Flashlight and batteries
- Fire extinguisher
- Duct tape (always)
And make sure your roadside assistance plan is up to date — just in case.
