RV winterization is crucial whether you’re storing your RV or planning a winter RV camping trip to one of America’s gorgeous national parks. Preparation is key to avoid costly damage from frozen pipes or cracked water tanks. Different types of RVs—motorhomes, travel trailers, etc.—require specific camper winterization steps to address their specific systems and features. Taking the time to winterize your RV correctly ensures it’s ready for RV storage or safe winter use. Before the temperatures start to drop, be mindful of your RV’s needs. Especially if you’re in an area with significant seasonal changes.

RV Winterization For Storage VS. Traveling In Winter

RV Winterization For Storage 

RV winterization depends on whether you’re storing your RV for the off-season or traveling during winter. For RV storage, the focus is on protecting your RV’s systems and preventing damage. This includes draining, adding antifreeze, and sealing gaps to keep out moisture and pests. On the other hand, when winterizing a camper for winter travel, your heating, insulation, and water systems remain functional. Finding the right RV storage location can make a big difference when protecting your camper during freezing weather. Indoor or climate-controlled storage helps shield your RV from ice, snow, and drastic temperature changes. This can help keep it in great shape for your trips in spring and summer.

Winterizing A Camper​ For Winter Travel

Preparing for winter RV trips requires extra attention to ensure your RV remains comfortable and functional in cold weather. When camping in freezing temps, RV winterization is essential, requiring you to actively maintain warmth and functionality.

Key steps include:

1. 1. Heating Systems: Ensure your furnace, space heaters or alternative heat sources are in good working condition. Clean or replace furnace filters and test the system before heading out. For a backup, consider portable propane or electric heaters as supplemental heat sources.
   2. Insulation: Optimize insulation by sealing drafty areas and adding thermal window coverings or reflective insulation. Foam pipe insulation and skirting around the base of the motorhome can help retain heat and prevent your undercarriage from freezing.
   3. Water Systems: Keep water lines from freezing by using heated hoses and heat tape. Some RVers use tank heaters or pads to keep fresh, gray, and black tanks operational in freezing temperatures.
   4. Power and Fuel: Bring backup power options, like a portable generator or solar panels. You should also check that your propane tanks are filled so you can heat your RV and cook meals.
   5. On-the-Road Safety: Bring tire chains or traction mats and monitor road conditions closely while traveling in your RV during winter. Snow shovels and ice scrapers are also great to have. 

Focusing on these areas can help you stay warm, protect your systems, and enjoy snowy adventures in your RV.

Winterizing A Motorhome

Class A RV Winterization

Winterizing a motorhome requires special attention to its unique features compared to other RV types. Class A motorhomes, with their larger size and more complex systems, demand thorough preparation to ensure they withstand freezing temperatures. Start by draining and cleaning your water tanks, including the fresh, gray, and black tanks, to prevent freezing and damage. You can protect the plumbing lines by adding RV-specific antifreeze, ensuring it flows through faucets, toilets, and showers. To minimize heat loss during winter, insulating the expansive windshield area with thermal covers is a clever tip. Additionally, run the generator with stabilizer-treated fuel to winterize it and keep it functional. Check and seal slide-out gaskets to prevent drafts and maintain a cozy interior. If you’re winterizing a motorhome for storage, focus on fully draining systems and protecting lines. However, preparing for winter RV camping trips involves additional steps, like ensuring that heating systems and insulation are optimized for active use. By focusing on these steps, RV winterization for a Class A motorhome ensures your vehicle is ready for storage or safe winter travel, setting it apart from towable RV types.

Class B RV Winterization

Winterizing a Class B motorhome is different compared to Class A’s due to the compact size and van-style design. One key step in RV winterization is disconnecting and storing all external hoses to prevent freezing and damage. Unlike larger motorhomes, Class B’s may require the use of insulated skirting or portable heaters to maintain internal warmth. If you’re planning on staying in your Class B during winter, having a portable heater is a must. 

You’ll also need to add RV-specific antifreeze to the internal plumbing system. Class B’s with portable showers and toilets often have smaller tanks and hoses that are more susceptible to freezing temperatures. You can then protect the van batteries by using trickle chargers or disconnecting them if the camper is in storage. Additionally, take advantage of the compact layout by using thermal curtains or window insulation to minimize heat loss. Be mindful of areas such as side doors and roof vents, where drafts are more likely in Class B motorhomes. Also, regularly check the seals on windows and doors for gaps that can let in cold air. By focusing on these aspects, you can winterize a camper of this size. 

RV Winterization​ for Towable RVs

Winterizing A Travel Trailer​

Begin by thoroughly draining and flushing the fresh, gray, and black water tanks and plumbing lines before applying RV-specific antifreeze. Unlike motorhomes, travel trailers typically have removable propane tanks, which should be disconnected, inspected, and stored. Make sure you put your propane tanks in a safe and well-ventilated area. If you plan on traveling during the winter, you’ll want to bring extra propane with you to stay warm. To prevent tire cracking in cold weather, you can cover your tires and check for proper inflation. Insulating vents, windows, and doors are also important, especially since travel trailers often lack the large heating systems found in motorhomes.

Travel trailers also have a more compact build, which means space heaters or skirting might be necessary. Additionally, lightweight materials and manual slide-outs make travel trailers more susceptible to drafts, requiring extra sealing for slide-outs and doors. Taking these steps will protect your travel trailer during storage or make it cozy and functional for winter camping adventures.

Fifth Wheel RV Winterization

Winterizing a fifth wheel differs from a travel trailer because of the structural and design differences. Fifth wheels have larger living spaces, additional slide-outs, and more advanced plumbing and heating systems than travel trailers. These differences require slightly separate approaches to RV winterization. Fifth wheels typically have more complex plumbing systems, similar to motorhomes, that often have appliances like dishwashers or washing machines. Winterizing these appliances involves bypassing water lines and running antifreeze through them. Fifth wheels often have additional slide-outs and larger windows that need weatherstripping. To help minimize heat loss, you can also buy thermal curtains or window covers.

Many fifth wheels feature a heated basement or underbelly storage area where tanks and plumbing are located. These areas may already have some insulation, but adding heated tank pads or pipe heaters is still crucial. Travel trailers usually lack these features. However, like travel trailers, you should also cover the tires on your fifth wheel to prevent cracking. Also, make sure the hydraulic leveling system works. Unlike other RV types, fifth-wheel RVs frequently have dual propane systems to power heating appliances and furnaces. These systems need to be checked, and propane tanks should be securely stored, or topped off for winter use. By addressing these differences, you can effectively winterize your fifth wheel to meet all RV winterization requirements.

How To Winterize A Pop-up Camper

Winterizing a pop-up camper presents unique challenges due to its light weight and, often, canvas construction. Winterizing a pop-up camper starts with removing and cleaning the canvas material before storing it in a dry, temperature-controlled area. Unlike larger RVs, pop-up campers often rely on portable water systems, so it’s essential to drain all water. This will prevent them from freezing. Additionally, you should also seal any gaps or openings in the structure to keep out pests and cold drafts. Batteries should be removed and stored in a warm, dry location to maintain their lifespan. By taking these steps, RVers can ensure their pop-up camper stays in great shape during the colder months.

Also, don’t think that just because you have a pop-up camper, you have to winterize and store it. You can add thermal liners or tarps to insulate the canvas and still go winter camping. Seal gaps and use RV antifreeze to protect your water systems. You should also bring portable water tanks and a heater for added comfort, plus additional power like extra propane tanks. With these RV winterization steps, you can enjoy cozy winter adventures.

Your checklist should include draining water tanks, adding antifreeze to plumbing lines, insulating, and sealing any gaps. With the right tools and preparation, RV winterization becomes an easier and more efficient process, allowing you to store or confidently embrace winter camping.

Common Mistakes to Avoid When Winterizing A Camper​

Effective RV winterization requires attention to detail, but some unique and often overlooked mistakes can compromise your efforts. A common misstep is forgetting to bypass the water heater before adding antifreeze, which wastes antifreeze and damages the heater. Similarly, failing to clean and dry out the refrigerator or freezer can lead to mold and unpleasant odors during storage. People often neglect to winterize slide-out seals, leaving them vulnerable to cracking and letting moisture seep in. Overlooking areas like the outdoor kitchen or external showers is another frequent error. These plumbing lines are just as exposed as the rest of the system. Another common mistake is not checking your RV’s manual for specific RV winterization guidelines. Each RV model may have unique features or systems that require extra care. Lastly, not lubricating hinges, locks, and leveling jacks can lead to rust and issues when it’s time to hit the road again. Don’t fall for these common mistakes, and make sure your RV stays in great shape through the winter season.
