Winter is coming. Actually, depending on where you are, it might already be here. But that means it's time to start thinking about winterizing your RV, especially if you want to avoid costly repairs in the spring. Proper winterization protects your plumbing system, appliances, seals, and other exterior components from freeze damage. A little preparation now can prevent cracked pipes, burst tanks, and premature wear throughout your rig, paying off well after winter has passed.
So here are five practical, no-nonsense steps to take to get your rig winter-ready.
1. Drain and flush the water system
This is the most important step to take to prepare your RV for the winter. Water expands when it freezes, and even a little can be enough to cause pipes and tanks to burst.
To drain the water system, start by turning off the water pump and disconnect from city water. Then, open every single faucet and drain — shower, toilet, low-point drains, everything — until the system runs completely dry. Once drained, you can flush the lines with RV-safe antifreeze to protect the system against freezing temperatures.
2. Insulate exposed pipes and holding tanks
Even after draining, there could be residual water left over in the system. Since even a small amount of water freezing can cause damage, adding insulation provides an extra layer of protection when your RV is left unused for a while.
Foam pipe sleeves work well for exposed plumbing, and you can use protective panels or even bubble wrap or another insulating material to protect your tanks.
3. Winterize your appliances
You probably have several appliances inside your RV that also need to be protected against the freezing temperatures of winter.
-
Water heater: Drain the tank completely, bypass it, and use RV antifreeze in the lines.
-
Refrigerator and freezer: Empty, defrost, clean, and leave doors cracked open to prevent mold.
- Air conditioner: Remove the drain plug to let condensation escape, then cover the unit.
4. Protect your tires and wheels
Cold weather can lead to underinflation, dry rot, and flat-spotting. If you’re storing the RV outdoors:
- Inflate tires to the recommended PSI.
- Use tire covers to block UV exposure.
- Move the RV slightly every few weeks, if possible.
If indoor storage is available, it provides even better protection during long-term winter storage.
5. Cover your RV
A quality RV cover prevents snow, ice, debris, and moisture from collecting on the roof and seams. Choose a breathable, weather-resistant cover designed specifically for RVs to prevent mold and reduce wear on exterior surfaces.
If you prefer using a tarp, secure it tightly and avoid direct contact with sharp edges to prevent tearing.
Upgrade for better sleep next season
If you want to use the winter downtime to make your RV more comfortable, upgrading your mattress is one of the easiest changes you can make. A custom RV mattress can dramatically improve your sleep quality once you’re back on the road. Our mattresses are built specifically for RVs, offering better support, durability, and comfort than standard options.
