How To Winterize Your RV

November 23, 2022

Winter is coming, and for many RV owners, that means it’s time to start thinking about winterizing their vehicle. Whether you’re a full-time RVer or just use your RV occasionally, taking the necessary steps to protect your investment during the colder months can save you from costly repairs down the road.

To help you get started, this article will provide some tips on how to properly winterize your RV.

From draining water tanks and adding antifreeze to protecting exterior components from harsh weather conditions, we’ll cover everything you need to know to ensure your RV stays in top shape throughout the winter season.

So grab a cup of hot cocoa and let’s dive into the world of winterization!

Preparing Your Water System

Winterizing your RV is a crucial step in keeping it functional and damage-free during the colder months. One of the most important aspects of winterization is preparing your water system to prevent any freezing or bursting pipes.

There are two main methods for this: blowing out and antifreeze method, but which one is best for you?

Blowing out your water system involves removing all the water from the pipes and tanks using compressed air. This method is preferred by some as it does not involve adding chemicals to the water supply. However, it can be time-consuming and requires access to an air compressor. If you choose this method, make sure to open all faucets, drain valves, and low points to ensure that every bit of water is removed.

On the other hand, antifreeze method involves pumping non-toxic RV antifreeze through your entire water system until it comes out of every faucet. This ensures that even if there are still pockets of water left in your pipes, they won’t freeze and cause damage. While this method may seem easier than blowing out, it does require purchasing several gallons of antifreeze.

Now that you’ve chosen your preferred method for winterizing your RV’s water system let’s move on to protecting its exterior from harsh weather conditions.

Protecting Your RV’s Exterior

Now that you’ve prepared your water system, it’s time to move on to the next important step in winterizing your RV.

This includes taking care of your tires and windows to ensure they are protected from cold temperatures.

Winterizing RV tires is crucial because cold weather can cause them to deflate or crack.

To avoid this, make sure your tires are properly inflated before storing your RV for the season.

You should also consider investing in tire covers, which will protect them from harsh elements such as snow and ice.

Another essential part of winterizing your RV is protecting its windows.

Cold air can cause window seals to contract and crack, leading to leaks and costly repairs down the line.

To prevent this, apply a protective film over each window or cover them with insulating material specifically designed for this purpose.

As you prepare for winter storage, don’t forget about storing your RV properly.

This means finding a dry and covered location where it won’t be exposed to extreme temperatures or moisture.

It’s also important to disconnect all batteries and appliances, drain any remaining fluids from tanks and pipes, and secure all doors and windows tightly.

With these steps complete, you’ll be able to rest easy knowing that when warm weather returns, your RV will be ready for another adventure!

Storing Your RV Properly

Cleaning is an important step when storing your RV properly. It’s best to start with the interior, making sure to get rid of all food crumbs and any dirt or dust that’s collected.

Then, you’ll want to move outside and scrub away any grime or mildew that’s built up on the exterior.

Drainage is also key. Remove any tanks that are still filled with water, then flush out the toilet and hook up an antifreeze solution to the drain. This will ensure that no pipes freeze and burst during the winter.

Finally, you’ll want to cover your RV with a tarp or breathable cover. This will protect it from the elements and keep critters from making a home inside. Make sure the cover is properly secured to keep it from blowing away.


Winterizing your RV is an essential step to ensure that it remains in good condition throughout the cold season.

One crucial aspect of winterizing involves deep cleaning the interior and exterior of your vehicle before storing it away. This process helps prevent dirt, debris, and moisture buildup, which can lead to mold growth or rusting.

To begin with, start by removing all personal items from the RV’s cabin space. Afterward, use a vacuum cleaner to remove any accumulated dust and dirt particles on the floors, walls, and ceiling. Pay extra attention to corners where cobwebs tend to accumulate.

Next up is upholstery care: clean your furniture using suitable products recommended for each material type like leather conditioner or fabric cleaners for fabrics.

Lastly, give special attention to areas prone to moisture accumulation such as the bathroom and kitchen spaces – wipe down surfaces thoroughly with disinfectant wipes or solution. Also, don’t forget about the exterior- wash off any grime or road salt deposits that could cause corrosion during storage.

Following these steps through deep cleaning and taking care of upholstery will go a long way in ensuring your RV stays in top shape over winter until you’re ready for your next trip!


Now that you’ve deep cleaned your RV, it’s time to move on to the next step of properly storing it away for winter. One important aspect of this process is ensuring proper drainage. Insulating pipes and using antifreeze can help prevent any damage to your plumbing system caused by freezing temperatures.

Before draining your water system, make sure to turn off all valves and disconnect any hoses or filters attached to your RV. Then open up all faucets and taps both inside and outside the vehicle to let out any remaining water. You may need to use an air compressor or a hand pump with a compressed air attachment to force out any trapped liquid in the lines.

After draining everything thoroughly, add some antifreeze into each drain trap as well as the toilet bowl and tank. This will help protect these areas from freezing temperatures during storage. Remember not to pour antifreeze into freshwater tanks, however- only use it in areas where wastewater flows through.

Draining your RV’s water system correctly can save you from costly repairs due to burst pipes come springtime. By insulating pipes and utilizing antifreeze where necessary, you can rest assured knowing that your plumbing system is protected until you’re ready for another adventure!


Now that you’ve taken care of draining your RV’s water system, it’s time to move on to the next step of properly storing it away for winter.

One important aspect of this process is covering your RV with a suitable cover. There are different types of covers available in the market, including custom-fit and universal covers.

The benefits of covering your RV include protection from various weather conditions such as rain, snow, and hail. It also helps prevent damage from UV rays and bird droppings. A good quality cover can extend the life of your RV by keeping it clean and reducing wear and tear caused by exposure to elements.

When choosing a cover, make sure to measure your RV accurately to ensure an optimal fit. Custom-fit covers may be more expensive but they provide better coverage compared to universal ones. Investing in a high-quality cover now will save you money in the long run by avoiding costly repairs or replacements due to damage caused by harsh weather conditions during the storage season.

Checking And Maintaining Your Batteries

Testing the voltage of your RV’s batteries is crucial before storing it for winter. You can use a multimeter to test the voltage, and if it reads less than 12 volts, you need to charge your battery fully. Make sure that you disconnect all electrical connections while testing the voltage.

Replacing terminals should be done if there are any signs of corrosion or damage. Corrosion buildup on terminals leads to reduced power supply, and damaged terminals can cause short circuits in your system. It is best to replace them with new ones before storing your RV for winter.

Battery maintenance is essential for longevity and performance. Regular cleaning and inspection help maintain optimal functioning of the batteries. Use baking soda and water solution to clean off any acid build-up from the surface of the terminals regularly.

Troubleshooting battery issues could save you a lot of time and money. If you notice anything unusual such as slow starting, dimming headlights or cabin lights not working correctly, immediately check the battery’s condition. Proper diagnosis will identify problems early enough for quick solutions or replacements.

Now that we have discussed checking and maintaining your RV’s batteries let us move on to other winterization tips and tricks that will help keep your RV safe during storage season.

Other Winterization Tips And Tricks

Now that you have checked and maintained your batteries, it’s time to move on to other important winterization tips for your RV.

One of the first things you should consider is investing in RV skirting. This will help keep the cold air out from underneath your RV and prevent heat loss. Additionally, it can help reduce drafts inside your RV.

Another tip is to insulate your windows properly. You can do this by using bubble wrap or window insulation film. Both options are affordable and easy to install, providing an extra layer of protection against the cold weather outside.

Lastly, don’t forget about protecting any exposed pipes or hoses from freezing temperatures. To do this, simply wrap them with foam pipe insulation or use heat tape to prevent them from freezing over during a cold snap. Use a thermostat to control the heat tape and prevent overheating.


In conclusion, winterizing your RV is a crucial step in ensuring that it remains in top shape throughout the cold season.

By following these simple steps, you can protect your investment and enjoy peace of mind knowing that your home on wheels is safe from the harsh elements.

So bundle up and get to work! With just a little bit of effort, you’ll be able to wrap your RV in a cozy blanket of protection that will keep it warm and dry until spring arrives.

Remember, just like a bear hibernating for the winter, your RV needs some tender loving care too.

So snuggle up with a cup of hot cocoa and let the snow fall outside while you rest easy knowing that your trusty travel companion is ready for whatever Mother Nature has in store.
