RV Winterization at a Glance:
How Do You Winterize RV Water Lines?
Winterize RV water lines by following the owner’s manual for draining tanks, lines, and the water heater. In freezing climates, the manufacturer may recommend a non-toxic RV antifreeze process to prepare the plumbing system.
Use this process:
- Drain the fresh-water tank according to the owner’s manual.
- Empty gray-water and black-water tanks using the manufacturer-recommended process and local disposal guidance.
- Review instructions for draining or bypassing the water heater.
- Follow the manufacturer’s process for clearing water from plumbing lines.
- Use RV-specific non-toxic antifreeze only when the manufacturer recommends it.
- Check the plumbing system before parking the RV for storage.
Do not use automotive antifreeze in RV plumbing systems.
How Should You Clean an RV Before Storage?
Clean an RV before storage by removing food, trash, moisture, and loose belongings from the interior. Vacuum floors and upholstery, clean kitchen and bathroom surfaces, and let all areas dry fully before closing the RV.
Before storage:
- Remove food, beverages, perishables, and liquids that could freeze.
- Empty cabinets, drawers, and storage compartments.
- Clean the refrigerator according to manufacturer instructions.
- Clean and dry bedding, towels, and linens before putting them away.
- Vacuum floors, seating, and storage areas.
- Check windows, doors, seals, and openings for visible gaps or maintenance needs.
- Wash and dry the RV exterior.
Do not leave food, wet items, household cleaners, fuel containers, or hazardous materials inside the RV or storage space.
How Should You Prepare RV Tires for Winter Storage?
Prepare RV tires by checking their condition and inflating them according to the RV or tire manufacturer’s recommended pressure. Inspect tires for visible wear, cracks, or other concerns before parking the RV.
Park the RV on a level, dry surface. Follow manufacturer guidance for tire covers, wheel blocks, pads, jacks, or other vehicle-support methods.
Tire covers can limit direct sunlight exposure during outdoor storage. Check tire condition again before taking the RV on the road after winter storage.
How Should You Prepare RV Fuel for Storage?
For a motorized RV, follow the manufacturer’s recommendations for long-term fuel storage. Depending on the RV and storage period, the process may include a specific fuel level or a compatible fuel stabilizer.
Follow both the RV manufacturer’s and fuel-product instructions. Complete fuel-system preparation before moving the RV into storage.
Never run an RV engine inside a storage unit or other enclosed space. Do not bring fuel containers, fuel stabilizer, oil, or hazardous materials into the storage space.
Should You Disconnect RV Batteries for Winter Storage?
Follow the RV manufacturer’s instructions for winter battery care. Some RVs may require house batteries, starting batteries, or other battery systems to be disconnected or removed during extended storage.
If the manufacturer recommends battery removal, store batteries at home according to battery manufacturer guidance. Loose batteries cannot go inside a Public Storage unit.
Do not use a battery maintainer or other electrical equipment at an RV storage space unless the location specifically confirms it is allowed.
How Do You Prevent Moisture in an RV During Storage?
Prevent moisture in an RV by cleaning and drying the interior fully before storage. Check the owner’s manual for ventilation recommendations because the appropriate setup can vary by RV type and climate.
Before storage:
- Dry the kitchen, bathroom, shower, and storage compartments.
- Remove damp towels, bedding, and clothing.
- Check windows, doors, roof seams, and exterior access points.
- Follow manufacturer guidance for vent covers and airflow.
- Check the RV periodically for moisture or exterior changes.
Use vent covers only when they fit the RV and follow manufacturer installation guidance.
What Should You Check Before Storing an RV?
Complete a final RV walkthrough before leaving the vehicle for the season.
Check that you have:
- Drained and prepared the plumbing system
- Removed food, beverages, trash, and liquids that could freeze
- Cleaned and dried the interior

- Reviewed manufacturer fuel-system guidance
- Managed batteries according to the owner’s manual
- Checked windows, doors, seals, roof areas, and exterior openings
