How to Prepare Your RV for Storage in Jacksonville’s Summer Heat
Jacksonville summers are no joke. With temperatures regularly pushing past 95°F and humidity levels that make the air feel like a warm wet towel, storing an RV in Northeast Florida requires more preparation than most owners realise. Whether you’re parking your rig between road trips or putting it away for a few months, skipping the prep work can mean expensive damage waiting for you when you come back.
Here’s exactly what to do before you hand your RV over to storage — and why Jacksonville’s climate makes each of these steps non-negotiable.
Why Jacksonville’s Climate Is Hard on Stored RVs
Most RV storage guides are written with northern winters in mind. But Florida presents its own set of challenges. UV radiation is intense year-round, meaning rubber seals, roof membranes, and exterior finishes degrade faster here than almost anywhere else in the country. Humidity creates the perfect conditions for mould, mildew, and rust to take hold inside and underneath your vehicle. And heat — sustained, relentless heat — causes tyre dry rot, battery drain, and fluid breakdown at an accelerated rate.
If you’re storing your RV in Jacksonville without addressing these factors, you’re rolling the dice every time.
Step 1: Clean It Thoroughly Inside and Out
Before your RV goes into storage, clean it as if you’re selling it. Any food residue left inside will attract pests. Moisture trapped in fabric, carpet, or mattresses will turn to mould within weeks in Jacksonville’s humidity. Wipe down every surface, vacuum thoroughly, and leave moisture-absorbing products like DampRid inside to manage humidity levels during storage.
On the exterior, wash the roof, sidewalls, and undercarriage. Pay close attention to any seams or seals — if you spot cracking or separation, reseal them before storage. UV damage exploits any existing weakness.
Step 2: Protect Your Tyres
Tyre dry rot is one of the most common and costly RV problems in Florida storage. The culprit is prolonged UV exposure combined with the weight of the vehicle pressing down on stationary tyres over time.
To protect them, inflate tyres to the manufacturer’s maximum recommended PSI before storage — tyres naturally lose pressure over time and you want to start at the top. Use tyre covers on any tyres exposed to direct sunlight. If possible, place the RV on tyre cradles or move it slightly every month to prevent flat spots from forming.
Step 3: Sort Out Your Battery
Florida heat kills batteries faster than cold weather does. If you leave your RV battery connected and unattended in summer storage, you may come back to a dead or damaged battery.
Disconnect the battery completely and either store it indoors or connect it to a trickle charger or battery tender. If you’re using a storage facility with power access, a smart charger that monitors and maintains charge levels is the best investment you can make for long-term storage.
Step 4: Address the Fuel System
For storage periods longer than 30 days, add a quality fuel stabiliser to your tank and run the engine for 10–15 minutes to let it circulate through the system. This prevents the fuel from breaking down and leaving varnish deposits in your carburettor or injectors — a repair that can run into hundreds of dollars.
Top the tank off close to full as well. A partially empty tank allows condensation to form inside, introducing water into your fuel system over time.
Step 5: Seal Every Opening
Florida is home to palmetto bugs, wasps, mice, and a remarkable variety of creatures that would love to make your stored RV their home. Before storage, inspect and seal every potential entry point — roof vents, exhaust pipes, air intakes, and any gaps around utility connections.
Use vent covers and place pest deterrents inside and underneath the vehicle. A single mouse in a stored RV can cause thousands of dollars in wiring damage.
Step 6: Choose the Right Storage Environment
All of the prep in the world is partially undone if your RV is sitting in direct Jacksonville sun for months on end. Covered RV storage protects against UV damage, bird droppings, and the elements — and in a climate like ours, the extra cost is genuinely worth it.
