Your RV is an investment you enjoy all summer. You need to winterize it to protect it during the cold months and prevent expensive repairs in the spring. These tips help you store your RV properly this winter.
Renew Registration and Insurance
Most RV storage facilities require proof of registration and insurance. Renew these essential documents now and review any storage requirements, including coverage details, at Storage/Winterization Coverage.
Inspect the Vehicle
Perform a visual inspection of your RV and take it for a short test drive. Identify and fix any mechanical, electrical, or body issues before you store the vehicle for the winter to avoid bigger problems later.
Clean the RV
Remove perishable food, wipe all surfaces, and vacuum the interior. Clean the exterior and undercarriage to remove dirt and road salt that can cause corrosion during storage.
Drain the Water Heater and Lines
Empty the water heater to protect it when temperatures drop to freezing. Blow out the fresh water lines or add RV-safe antifreeze, and remember to drain the shower, toilet, washing machine, ice maker, and dishwasher water lines as well.
Protect the Battery
An RV battery can freeze as it loses charge or is exposed to moisture. Ideally remove the battery and store it in a warm, dry place; otherwise set up a continuous charger or start the RV every month to maintain the charge.
Increase Tire Pressure
Cold weather and long periods of inactivity can damage your RV’s tires. Increase tire pressure by about 10 psi before storage or lift the vehicle off the ground to remove excess weight and help preserve the tires.
Prevent Critter Access
Mice and other critters may see your RV as a cozy shelter during winter and can cause costly damage. Seal all potential entrances, store food in airtight containers, and set humane or legal traps inside the RV as needed.
Reduce Roof Damage
Heavy snow and ice can damage the exterior and break lights or vents on the roof. Place sheet metal or a wooden box over skylights and the refrigerator vent for protection where appropriate.
Ensure Proper Ventilation
Moisture buildup inside the RV can lead to mold and mildew. Improve air circulation by leaving appliance doors, the roof vent, or side windows open slightly and consider a small dehumidifier for enclosed storage spaces.
Secure a Cover
A breathable, water-resistant RV cover protects the exterior from snow, ice, and wind. Place cardboard over sharp edges before fitting the cover, choose one with a zip-in door if you need occasional access, and secure it so it doesn’t flap and damage paint or decals.
If you store your RV at a park or commercial facility, confirm their insurance requirements and consider specialized policies like RV Park Insurance. If you have questions about coverage or options, talk to an agent.
Frequently Asked Questions
When should I winterize my RV?
Winterize before temperatures regularly fall below freezing in your area or before storing the RV for extended periods; timing depends on local climate.
Do I need to use RV antifreeze throughout the entire plumbing system?
Yes—if you choose antifreeze over blowing out lines, be sure to run RV-safe antifreeze through all water lines and drains, including shower, toilet, and appliances.
Can I leave the battery in the RV during winter?
You can leave it in place if you use a continuous charger and ensure it stays above freezing, but removing and storing it in a warm spot is best for longevity.
How do I keep mice and rodents out of my RV?
Seal gaps and vents, remove food sources, and place traps or deterrents in likely entry areas to reduce the risk of infestations.
