How to Store Your RV for Winter in the South: A Complete Checklist

How to Store Your RV for Winter in the South: A Complete Checklist

1. Drain tanks and winterize the plumbing.

2. Prepare the battery for storage.

3. Check tire pressure and protect tires.

4. Clean, dry, and control interior moisture.

5. Remove food and block pest entry points.

6. Inspect exterior seals and choose a properly fitted RV cover if needed.

Southern winters may be shorter, but your RV still needs a storage plan.

Hey Happy Campers! Around the Gulf South, putting an RV away for winter looks a little different. Some families park after football season. Others squeeze in a holiday trip before taking a break. Either way, knowing how to store an RV for winter means preparing for the weather that could arrive while it sits.

In Louisiana, Mississippi, Alabama, and the Florida Panhandle, that means thinking about humidity, rain, and sudden freezes. A warm afternoon does not tell you what your water lines will experience during the next cold front.

Use this RV winter storage checklist before parking, whether your next trip is weeks or months away.

1. Drain Your Tanks and Protect the Entire Water System

Start by emptying and flushing your black and gray tanks at an approved dump station. Drain the freshwater tank and follow your RV manufacturer's winterization instructions for the plumbing system.

Draining the freshwater tank alone does not remove water trapped in the pump, faucets, toilet valve, or appliances. Make a list of everything connected to water, including:

• Kitchen and bathroom faucets.

• Indoor and outdoor showers.

• Toilet and sprayer.

• Water pump, strainers, and filter housings.

• Refrigerator ice maker or water dispenser.

• Washing machine, dishwasher, and black tank flush, if equipped.

Your water heater needs its own attention. Turn it off, let it cool, and relieve pressure before draining a tank-style heater. Follow its bypass instructions when winterizing. Tankless heaters have different procedures; follow the specific appliance manual rather than assuming the same steps apply.

Use only antifreeze labeled for RV potable-water system winterization when your procedure calls for it. Never substitute automotive antifreeze. Protect drain traps and toilet seals as directed by the manufacturer, too.

If using compressed air, follow the approved pressure limit and procedure for your equipment. Blowing out a few faucets does not establish that every component is protected.

Gulf South climate note: Plan before freezing weather reaches an unattended RV. Freeze damage depends on temperature, exposure, duration, and the RV's construction. There is no universal number of hours that makes every RV safe. A covered parking space does not automatically protect the plumbing from freezing.

2. Make a Battery Storage Plan

A battery left connected can lose charge while the RV sits. Equipment may continue drawing power even when the lights and appliances appear off.

First, identify your battery type. Flooded lead-acid, AGM, and lithium batteries have different charging and storage requirements. Follow the battery manufacturer's recommended storage charge and temperature limits.

If the RV will sit without electricity, determine whether to isolate or remove the battery according to your equipment's instructions. Do not assume the battery disconnect switch shuts off every circuit. Some wiring may bypass it.

If you keep the RV plugged in, confirm that the converter or charger is compatible with your battery and suitable for extended charging. Shore power is useful only when the charging system is operating correctly.

Solar also needs checking. A covered RV, shaded parking spot, or dirty panel may change how much charging is available.

Motorhomes may have separate chassis and house batteries. Include both in your plan, and schedule charge checks rather than discovering a dead battery before departure.

3. Check Tires and Choose a Good Parking Surface

Before parking, inspect your tires for cracks, bulges, uneven wear, and other damage. Check cold inflation pressure against the RV manufacturer's guidance and applicable tire load information. Do not guess from how the sidewalls look.

Choose a firm, well-drained storage surface whenever possible. A spot that stays muddy after rain creates problems for access and support. Look overhead for damaged limbs and consider where rainwater collects.

Use wheel chocks and follow your RV's instructions for leveling and stabilizer placement. Stabilizer jacks are not automatically approved for lifting the RV or taking its weight off the tires.

Tire covers can help shield tires from sunlight during outdoor storage. Recheck pressure before the next trip, even if the tires looked fine when you parked.

Walk around the storage space before committing to it. Leave enough room to inspect both sides, open necessary compartments, and retrieve the RV without a difficult maneuver.

4. Clean, Dry, and Control Moisture

In the South, moisture deserves as much attention as cold weather. Storing an RV with damp towels, wet carpet, or an unnoticed leak gives problems time to grow.

Clean the interior thoroughly and let surfaces dry before closing up. Empty the refrigerator and freezer, turn them off, and clean and dry them. Use the appliance's storage latch or approved method to keep doors slightly open.

Check under sinks, around windows, inside cabinets, and along slideout corners for signs of water. A stain or musty smell deserves investigation before storage.

Choose a moisture-control approach that fits your parking arrangement. Moisture absorbers need replacement or emptying. A dehumidifier needs reliable electricity, proper placement, and a dependable drainage plan. Neither fixes an active leak.

A small humidity monitor can help you spot a developing problem during visits. Check upholstery, mattresses, and enclosed storage areas rather than relying only on how the main living area smells.

Do not leave windows open and assume fresh air will solve humidity. Outdoor air may be damp, and an opening may admit rain. Follow the RV manufacturer's storage ventilation guidance.

5. Remove Food and Close Pest Entry Points

Before storage, remove food from the pantry, refrigerator, drawers, and exterior kitchen. Include pet food, birdseed, forgotten snacks, and crumbs under cushions.

Then inspect places where plumbing, wiring, and other components pass through floors or compartments. Look for damaged underbelly material, loose access panels, and gaps that could provide entry.

Use suitable repair materials for those openings. Avoid blocking required drains, ventilation, or appliance exhausts. Any appliance screens or protective accessories should be approved for that equipment.

Do not make a scented product your entire pest-control plan. Removing attractants, addressing entry points, and inspecting regularly gives you a more practical approach.

During storage visits, check for droppings, nesting material, damaged wiring, and chewed packaging. If you find evidence of pests, address it promptly. Leaving the RV parked for another month will not make the problem easier to solve.

6. Inspect the Exterior and Decide Whether to Cover It

Wash the exterior with products approved for your RV's surfaces. Inspect roof seams, vents, skylights, windows, compartment doors, and other sealed openings for damage or deteriorating sealant.

Have questionable areas evaluated before storage. Use compatible repair products; the wrong sealant can create another problem.

An RV cover can be helpful for outdoor storage, but fit and material matter. Choose a breathable cover designed for your RV's size and shape. Follow its instructions for straps, sharp edges, and installation.

A loose cover can move against the finish in windy weather. A poorly chosen covering can also trap moisture. Check it after storms instead of assuming it stayed secure.

Covered or indoor parking may reduce exposure, but it does not eliminate inspections. Retract and secure the awning, close compartments, and follow your RV's storage instructions for slideouts and propane. For motorhomes and generators, also complete the manufacturer's fuel, fluid, and storage requirements.

Frequently Asked Questions

Do I need to winterize if I live in the South?

Yes, if freezing conditions could reach your stored RV. Southern weather does not guarantee freeze protection. Prepare the water system before the cold arrives.

Should I disconnect my RV battery for storage?

Often, isolation is appropriate when no charging source is available, but follow your battery and RV manuals. Battery type, connected equipment, and charging arrangements determine the right plan.

How do I keep mice out of my RV?

Remove food, clean thoroughly, repair suitable entry points, and inspect regularly. Pest deterrents should support those steps rather than replace them.

Should I cover my RV?

Consider a properly fitted, breathable RV cover for outdoor storage. Your storage location, weather exposure, and manufacturer guidance should guide the decision.

Get Ready Before the Next Cold Front

Put a recurring storage visit on your calendar. Check for leaks, pests, moisture, battery issues, and cover damage, especially after storms or freezing weather.

Before leaving, take photos of your storage setup and write down which systems are turned off, where the battery is stored, and when you last checked the RV. Keep that record with your keys. If someone else checks the camper for you, share the list so they know what needs attention and what should stay disconnected until your next trip.

Pack hoses, cords, and accessories only after they are clean and dry. Label anything removed for storage so reinstalling it is straightforward. Before locking up, check every compartment and make one final pass through the interior. Bring home valuables and anything you will need between trips, rather than making an extra drive to retrieve it from an offsite storage lot.
