RV Maintenance to Prep for Summer: Your Easy Guide to a Trouble-Free Season

As the Arizona temps climb and road trip season rolls in, now’s the time to make sure your RV is in tip-top shape. A little prep work now can save you a lot of headaches later—whether you're headed to a national park, cross-country, or just staying close to home. Here’s a no-fluff guide to summer RV maintenance so you can hit the road with confidence. If you're looking for a safe spot to keep your vehicle between adventures, we offer convenient and secure RV storage right here in Arizona as well.

Why Summer RV Maintenance Matters

Summers in Arizona are no joke. The extreme heat, long miles, and dry air can push your RV to its limits. Staying ahead of the game with seasonal RV maintenance helps prevent unexpected breakdowns, keeps your systems running efficiently, and protects your investment for the long haul. Plus, you’ll enjoy a smoother, safer trip—without any surprise detours to the repair shop.

De-Winterize Your RV

Start by flushing out any remaining antifreeze from your water lines. Reconnect the water pump, open up all faucets, and run clean water through the system. Don’t forget to check for leaks while you’re at it. Turn on your water heater and make sure it’s operating properly. It’s also a good idea to reinstall any batteries or accessories you may have removed during winter storage.

Inspect and Inflate Your Tires

Tires are one of the most overlooked parts of RV maintenance—but one of the most critical. After sitting for months, tires can lose pressure or develop dry rot. Check the PSI and inflate them to the manufacturer’s recommended level. Look for any cracks, bulges, or uneven wear. While you're at it, don’t forget to check your spare tire too.

Test the A/C System and Ventilation

When Arizona’s heat is in full swing, a working A/C unit isn’t optional—it’s essential. Test the air conditioning early to make sure it's blowing cold and running efficiently. Clean or replace the filters and check for obstructions in your vents. If it’s been a while since your last service, now might be the time for a professional inspection.

Flush and Sanitize the Water System

Water quality can suffer if your tanks haven’t been cleaned since last season. Start by draining the freshwater tank completely, then flush the system with a mix of household bleach and water. Let it sit for several hours before flushing it out with clean water again. This helps eliminate bacteria and any lingering odors.

Deep Clean: Inside and Out

Give your RV a thorough clean, inside and out. Scrub the counters, floors, and bathroom areas. On the outside, wash and wax the body to protect it from sun damage. Pay extra attention to the roof and slide-out seals, which often get overlooked. Cleaning now helps you spot small issues before they turn into big ones later.

Slide-Outs and Seals: Check for Cracks and Lubricate

Extend each slide-out and inspect the seals for cracking or separation. Apply a quality seal conditioner to keep the rubber flexible and leak-free. Lubricate the moving parts with a dry lube spray to make sure everything slides smoothly and quietly.

Update Your Emergency and Tool Kit

Before you pack for your next trip, take inventory of your emergency supplies. Restock the first aid kit, replace expired items, and double-check that your tools are in good shape. Add essentials like extra water, sunscreen, bug spray, tire sealant, and duct tape—because you never know what the road will throw your way.

Smoke, Propane, and Carbon Monoxide Detectors

Safety first—always. Test all smoke detectors, carbon monoxide alarms, and propane leak detectors. Replace batteries and make sure your fire extinguisher is fully charged and accessible. These quick checks can save lives and are often overlooked during trip planning.

Electrical System and Battery Check

Take a close look at your battery. Clean the terminals and check the charge level. If your battery requires water, top it off with distilled water. Inspect all electrical connections and wiring for signs of corrosion or wear. If you use solar power, make sure your panels are clean and functioning correctly.

RV Roof and Exterior Inspection

Your RV roof takes a beating year-round. Check for cracks, soft spots, or peeling sealant—especially around skylights and vents. Reseal any problem areas to avoid water leaks. Walk around the exterior and look for any signs of damage, rust, or fading.

Holding Tanks and Waste System Maintenance

Empty and flush the black and gray water tanks, then clean them with a tank treatment. Enzyme-based cleaners help break down buildup and keep odors in check. Make sure all valves open and close smoothly, and inspect hoses for wear or cracks.

Refresh Your Packing List for Summer Travel

It’s a good idea to do a full gear review before hitting the road. Swap out cold-weather clothes for lightweight, breathable options. Restock cooking supplies, outdoor gear, and travel games. You’ll also want to make sure things like flashlights, batteries, and USB chargers are ready to go.

Schedule a Professional RV Service

Even if you’re a seasoned DIYer, it’s smart to have a professional take a look before a long summer trip. A certified RV tech can check your brakes, suspension, axles, and appliances to make sure everything’s road-ready. It’s one of those things that can save you a lot of money and stress down the line.
