If you've lived in Southern Utah for long, you know our outdoor lifestyle is unmatched—but our summer heat can be brutal on recreational vehicles.
Here in St. George, Utah, the RV community is huge. From weekend trips to Sand Hollow to cross-country adventures, your motorhome or travel trailer is your ticket to freedom. But anyone who has touched a steering wheel in August knows Southern Utah heat can be intense. Protecting your investment from the baking sun, dry climate, and dusty winds requires a bit of planning.
Quick Answer
The best way to store an RV in St. George is to use a covered RV storage facility that helps moderate exposure to direct Southern Utah sunlight and weather. To help prevent damage, use UV-resistant tire covers, maintain your batteries, seal vents against dust, and wash the exterior before parking. Sunbrook Secure Storage offers covered and uncovered RV, boat, trailer, and vehicle parking in St. George.
Key Takeaways
- Covered Storage Helps: Metal canopies help protect your RV from direct UV exposure and extreme Southern Utah heat.
- Tire Care is Essential: UV rays can dry out rubber, so use high-quality tire covers to help prevent sidewall cracks.
- Battery Maintenance: Disconnect batteries or use trickle-charge connections (available on select stalls at Sunbrook) to preserve battery life.
- Seal Against Dust: Close vents and windows tightly to keep out fine red dirt and pests.
Why Southern Utah Is Tough on RVs
Most people don't realize how quickly the desert environment can age an RV. With 100°+ summer temperatures, constant UV exposure, and a very dry climate, materials like rubber, vinyl, and fiberglass can degrade rapidly if left unprotected.
We've helped many local families with RV storage, and one thing we see all the time is premature tire aging and interior fading from sun baking through the windows. The wind and dust also have a way of finding every tiny crevice in your camper.
Tip #1: Cover Your RV Whenever Possible
The single best thing you can do for your motorhome or trailer is keep it out of direct sunlight. Covered RV storage in St. George is highly sought after for a reason. A metal canopy helps block the UV rays that cause fiberglass oxidation, roof degradation, and decal peeling. If covered parking isn't available, investing in a high-quality, breathable RV cover is your next best option.
Tip #2: Protect Tires

Tire rot is a massive issue in Washington County. The heat and UV rays dry out the rubber compounds, leading to dangerous sidewall cracks. Always use UV-resistant tire covers when your RV is parked for more than a few weeks. It's also smart to park on paved vehicle-storage areas rather than bare dirt to help prevent moisture and chemical wicking.
Tip #3: Care for Your Batteries
Extreme heat evaporates battery fluid and accelerates self-discharge. If you're storing your RV long-term, disconnect the batteries or remove them entirely and store them in a cool, dry place. Alternatively, look for a facility that offers trickle-charge electrical connections, which are available on select stalls at Sunbrook Secure Storage. The good news is, taking 10 minutes to manage your batteries now saves you a massive headache on your next departure day.
Tip #4: Seal Against Dust
Southern Utah dust gets everywhere. Before putting your camper into storage, close all roof vents, windows, and slide-outs tightly. Consider covering your AC unit and using vent pillows to block out both the fine red dirt and the extreme heat.
Tip #5: Keep Rodents Out
Desert mice and packrats love a cozy, undisturbed RV. Block any obvious entry points where plumbing or wiring enters the floor. Don't leave any food inside—not even dry goods or dog food. Removing the food source is the most effective strategy.
Tip #6: Empty Water Systems if Needed
While we worry more about freezing in the winter, stagnant water in the summer heat can quickly turn into a science experiment. Drain your fresh water tank and flush your black and gray tanks thoroughly before long-term RV storage.
Tip #7: Visit Your RV Occasionally
Don't just park it and forget it. Stop by every 4-6 weeks to run the generator (under load) for about 30 minutes, check for any signs of leaks or pests, and ensure your tires are holding pressure. It's like checking in on a good friend.
Tip #8: Wash Before Storage
Bugs, bird droppings, and tree sap become baked onto your RV's exterior in the St. George sun. Give your rig a thorough wash and apply a coat of UV-protectant wax before dropping it off at the storage facility.
Tip #9: Organize for Your Next Adventure
Take time to clean the interior, prop the refrigerator doors open to prevent mold, and organize your gear. When Friday afternoon rolls around and you're ready to head out, you'll thank yourself for leaving the RV in ready-to-go condition.
Tip #10: Choose a Secure Storage Facility
Finding secure RV storage in Southern Utah is essential. Look for a facility with keypad-controlled gate access, camera monitoring, and wide drive aisles so you aren't sweating bullets trying to back your 40-foot motorhome into a tight spot.

Frequently Asked Questions
Is covered RV storage worth it?
Covered RV storage in St. George helps protect your vehicle from intense UV rays, which can reduce the risk of roof damage, fading decals, and cracked seals over time.
Can the Utah sun damage an RV?
Constant exposure to Southern Utah's sun and 100°+ temperatures can degrade fiberglass, dry out rubber seals, cause tire rot, and fade the interior upholstery of your motorhome or trailer.
How often should I start my RV?
You should visit your stored RV every 4 to 6 weeks to start the engine and run the generator under a load for about 30 minutes. This keeps engine components lubricated and helps prevent fuel from going stale.
Should I disconnect my batteries?
If you are storing your RV for more than a few weeks without being plugged into a trickle-charge connection, disconnect the batteries to prevent parasitic drains from emptying them.
