Whether you’re storing your RV for the season or planning a few cold-weather adventures, preparing it for winter is one of the most important maintenance tasks you’ll perform all year. A little preparation now can prevent costly repairs, extend the life of your RV, and ensure it’s ready to hit the road when spring arrives.
Here’s everything you need to know to properly winterize your RV.
⸻
1. Drain and Protect Your Water System
One of the biggest risks during freezing temperatures is water expanding inside your plumbing system. Frozen pipes, cracked fittings, and damaged water heaters can lead to expensive repairs.
To protect your water system:
* Drain the fresh water tank.
* Empty and flush both the gray and black holding tanks.
* Drain the water heater.
* Open all faucets and low-point drains.
* Blow out the water lines with compressed air or use RV antifreeze designed specifically for plumbing systems.
Never use automotive antifreeze in your RV’s plumbing.

2. Clean Your RV Thoroughly
Before storing your RV, give it a complete cleaning inside and out.
Interior:
* Remove all food and beverages.
* Empty the refrigerator and freezer.
* Vacuum carpets and wipe down all surfaces.
* Leave cabinet doors slightly open for airflow.
* Place moisture absorbers inside to help prevent mold and mildew.
Exterior:
* Wash the roof, walls, and windows.
* Remove tree sap, bugs, and road grime.
* Apply a quality RV wax if needed.
* Inspect roof seals and caulking for cracks.
A clean RV is much less attractive to insects and rodents during storage.

3. Protect Your Batteries
Cold temperatures can shorten battery life if they aren’t properly maintained.
For best results:
* Fully charge your batteries before storage.
* Disconnect them from the RV.
* Store batteries in a cool, dry location if possible.
* Recharge them every month or use a quality battery maintainer.
Proper battery care can significantly extend their lifespan.

4. Inspect Tires Before Storage
Your tires support thousands of pounds, even while your RV is parked.
Before storing:
* Inflate tires to the manufacturer’s recommended pressure.
* Park on solid surfaces whenever possible.
* Consider using tire covers to protect against UV damage.
* If storing for several months, move the RV occasionally to prevent flat spots.

5. Seal Every Possible Entry Point
Small openings are invitations for mice, insects, and other unwanted guests.
Inspect around:
* Plumbing penetrations
* Electrical openings
* Storage compartments
* Roof vents
* Slide-outs
Seal gaps where appropriate and remove anything inside that could attract pests.

6. Protect Your Windows
Large RV windows are beautiful, but they are also one of the most vulnerable and expensive parts of your RV.
During winter storage, windows are exposed to:
* Snow and ice
* UV rays
* Tree branches
* Wind-blown debris
* Temperature fluctuations
Installing high-quality exterior window covers helps protect your glass while also reducing interior fading and improving insulation.
Custom-fitted window covers are especially valuable for large front cap windows and entry door windows, helping prevent damage that could otherwise result in costly replacements.

7. Cover Roof Vents and Openings
Roof vents can allow moisture, snow, and debris into your RV if left unprotected.
Vent covers help:
* Keep rain and snow out
* Improve airflow
* Reduce moisture buildup
* Protect vent components from UV exposure
This simple upgrade can help keep your RV dry throughout the winter months.

8. Reduce Interior Moisture
Condensation is one of the biggest causes of mold, mildew, and unpleasant odors.
To minimize moisture:
* Use moisture absorbers throughout the RV.
* Slightly crack roof vents if they’re protected by vent covers.
* Remove bedding and cushions if storing long term.
* Leave interior doors and cabinets open to improve airflow.
⸻
9. Check Your Propane System
Before storage:
* Turn off propane at the tanks.
* Inspect hoses for cracks or wear.
* Check regulators for corrosion.
* Store portable propane cylinders safely according to local regulations.
⸻
10. Perform a Final Walk-Around
Before locking the door for the season, do one last inspection.
Make sure:
* All windows and doors are securely closed.
* Storage compartments are locked.
* Awnings are clean and fully retracted.
* Stabilizer jacks are properly positioned.
* Exterior accessories are secured or removed.
Taking five extra minutes now can save hours of frustration later.
