Why is Winterizing Your Travel Trailer Important?

Winterizing your travel trailer is crucial for safeguarding your RV and ensuring its longevity, especially in regions where winters bring freezing temperatures and harsh weather conditions. If you don’t winterize properly, you will be signing yourself up for a host of problems. These can include frozen plumbing systems, leading to bursting pipes, costly repairs, and potential water damage within your trailer. Additionally, freezing temperatures can harm various components of your trailer's exterior, including seals, caulking, and even the frame.

If you're planning to live in your travel trailer during the winter months, the importance of winterization takes on added importance. Living in a trailer during the winter can be a cozy and adventurous experience, but it comes with unique challenges. Without properly learning how to winterize a travel trailer while living in it, you risk facing discomfort due to inadequate insulation, moisture buildup leading to mold and mildew, and excessive heat loss through windows and gaps. Moreover, frozen plumbing systems can leave you without access to essential amenities. That’s why you should be sure to winterize your RV properly so that your home on the road is warm, dry, and worry-free!

Tools You Will Need to Winterize Your Camper

If you are planning to winterize your camper by yourself, you will have to go digging for the right tools first. Check out our list below for all the items you will need to get started!

  • RV Manual:

Your RV manual is an invaluable tool for the winterization process. It provides specific instructions and insights tailored to your RV's make and model. Always consult it before starting the winterization process to ensure you follow manufacturer-recommended procedures accurately. This helps you avoid costly mistakes and protect your RV effectively.

  • RV Antifreeze:

RV antifreeze is designed to protect your plumbing system from freezing temperatures. The antifreeze has a lower freezing point than water, so it won't solidify in your pipes and cause damage. The amount you need will depend on the size of your camper to completely flush and fill your plumbing systems.

  • Water Pump Converter Kit:

A water pump converter kit is essential for efficiently pumping antifreeze into your plumbing system. It includes a hose and a valve that connects to your water pump. It's a more effective method than manually pouring antifreeze into each fixture, so be sure to look for one of these.

  • Socket/Wrench Set and Screwdrivers:

You will also need a socket and wrench set that includes various sizes and types of sockets and wrenches. This will be needed for removing and reinstalling components like drain plugs or water heater anodes during the winterization process. The screwdrivers are useful tools for removing screws and accessing components within your camper. They come in handy for removing access panels, accessing water pumps or bypass valves, and other tasks involved in winterizing your RV.

  • Plumbing Blowout Adapter:

The plumbing blowout adapter allows you to connect a compressed air source to your camper's water system. This helps ensure that there's no water left to freeze in the lines by blowing out the remaining water in the pipes, reducing the risk of damage. This is particularly important if you live in regions with extremely cold winters.

  • Pipe Insulation and Heat Tape:

To prevent freezing, consider insulating exposed water lines and pipes using pipe insulation. Heat tape can also be applied to vulnerable areas for additional protection. Proper insulation helps maintain warmth in key plumbing components, reducing the risk of freezing and impairment.

Bonus - RV Shade Canopy System:

If you plan to embark on a winter adventure in your RV, remember the forces that you will have to deal with during your travels. A quality RV shade canopy can be a game-changer. A RV roof shade helps to regulate the interior temperature during the winter and can also serve as a protective barrier against snow and ice, preventing excessive buildup on your RV's roof and exterior.

This added layer of insulation and protection can contribute to a more comfortable and efficient winter living experience in your camper. Plus, the RV canopy shade extends the lifespan of your RV's exterior by shielding it from the elements year-round. Not only that, an RV patio tent and an RV sun blocker, also come quite handy during winters. These products, with a canopy for RV the roof, can offer additional shelter and living space, allowing travelers to expand their usable area and enjoy the outdoors while staying protected from any extreme winter weather.

7 Steps to Winterize Your Travel Trailer

If this is your first time winterizing your trailer, the process can be confusing and complex at times. Here's a comprehensive guide with seven essential steps, including tips on how to winterize a travel trailer for living in, that covers everything from interior and plumbing to insulation and shading:

Drain all Water Systems:

Start by emptying your freshwater tank completely. Next, locate and drain the water heater. There's typically a drain valve or plug near the bottom. Open all faucets inside your camper, including both hot and cold water taps, to allow any remaining water to flow out. Also, locate and open the low point drains, which are typically found underneath the trailer, to release any residual water. Don't forget to flush the toilet to remove any water from the lines! Lastly, drain the black and gray water tanks following your manufacturer's instructions.

Bypass the Water Heater:

Locate the water heater bypass valve, which is typically located near the water heater itself. This valve allows you to redirect water flow around the water heater. Turn it to the "bypass" position, which is usually perpendicular to the water lines, to prevent antifreeze from entering the water heater.

Add RV Antifreeze:

RV-specific antifreeze is necessary to protect your plumbing from freezing. Connect a water pump converter kit to your water pump, then insert the kit's hose into a container of RV antifreeze. Turn on the water pump and open each faucet (both hot and cold) one by one until you see pink antifreeze flow out. Be sure to do this for every water fixture, including outdoor showers or any additional water connections.

Insulate Vulnerable Areas:

Insulating exposed water lines and pipes with pipe insulation helps maintain warmth and prevent freezing. Wrap the insulation snugly around the pipes, especially in areas where they are exposed to cold air. Heat tape can also be used on vulnerable areas for additional protection. Ensure that these measures are secure and properly sealed to maximize their effectiveness.

Seal Gaps and Cracks:

Thoroughly inspect the exterior of your trailer for any gaps, cracks, or areas with damaged seals. Use a caulking gun and a compatible sealant to seal these areas effectively. Pay close attention to seams, window frames, door frames, and any other openings that might allow drafts, moisture, or cold air to enter.

Protect Tires and Exterior:

Whether you plan to winterize the RV for storage or to live in, remember to inflate your trailer's tires to the recommended pressure as specified in your owner's manual or on the sidewall of the tires. Overinflated or underinflated tires can be problematic in cold weather. Consider using tire covers to protect them from sun exposure and prevent dry rot. To safeguard the exterior, clean your trailer thoroughly and apply a protective wax or sealant to prevent moisture damage and maintain its appearance.

Finally, cover your trailer with a breathable, weather-resistant shade for RV, designed to shield it from snow, ice, and UV rays. This helps to prolong the life of your camper and prevent weather-related wear and tear.

Install Window Insulation and Shades:

While living in the RV during the winter, you must try to prevent heat loss through windows. Consider installing thermal curtains or reflective window insulation that creates a barrier between the interior and exterior, helping you to maintain a comfortable temperature inside the trailer. A canopy for the RV roof, or RV sunshade cover, further prevents damage to the roof while also keeping you warm inside. You can also extend the RV shade cover and string up some RV outdoor lights to create an inviting space for yourself to enjoy a bonfire, making winter evenings cozy and memorable in the comfort of your RV's sheltered outdoor oasis.

What Are Your RV Storage Options?

When it comes to owning an RV, one of the most critical considerations is where to store it when you're not on the road. RV storage options are plentiful and vary in terms of convenience, cost, and accessibility. One popular choice is keeping your RV at home, provided you have the space and local regulations allow it. You might also find it necessary to build a sun shade for the RV roof to safeguard the vehicle's exterior from potential harm. Many RV owners invest in carports or dedicated RV garages to protect their vehicles from the elements. This option offers the advantage of easy access, but it may not be viable for those with limited space or stringent zoning restrictions.

Another common solution is renting an RV storage facility. These facilities offer secure, gated access, often with options for covered or uncovered storage. Renting a storage space can be particularly advantageous for those living in areas with harsh weather conditions, as it provides additional protection against sun, rain, and snow. Some RV storage facilities even offer amenities like dump stations and electrical hookups, making it convenient to prepare your RV for your next adventure. Ultimately, the choice of RV storage depends on your individual needs, budget, and the availability of suitable storage options in your area.


Whether you're preparing it for storage during the cold season or planning to live in it throughout the winter months, winterizing your RV is an important step that you can’t put off. So, take the time to prepare your RV for the cold and get ready to hit the road or hunker down in style when winter arrives! Follow our guide for a worry-free winter with your home on wheels so it’s good as new for the next camping season. Happy RVing!
