Step-by-Step Guide to Winterize the Camper

Now I’ll discuss the nitty-gritty of winterizing your camper. It’s all about keeping things simple and stress-free. I’ve broken down the process into easy-to-follow steps, so you won’t feel like you need an engineering degree. Whether you’re a seasoned RV enthusiast or just starting out, This step-by-step guide will have you winterizing your camper like a pro.

Gathering Materials

Winterizing your camper is like gearing up for a chilly adventure – you need the right tools in your arsenal. Before you start the winterization process, gather the materials you’ll need. Here’s your checklist for materials you’ll need:

  • Non-toxic RV Antifreeze

You’ll need 2-3 gallons of non-toxic RV antifreeze to protect your plumbing system from the winter freeze.

  • Basic Tools

These tools can include wrenches or pliers for removing and installing drain plugs. The goal is to be ready for any surprises that might pop up during the winterization journey.

  • Water Pump Converter Kit

You’ll need a water pump converter kit or basic tubing to connect the antifreeze to your system. It ensures a smooth flow of antifreeze through your camper’s veins.

  • Water Heater Bypass Kit

Some RVs come with a built-in water heater bypass kit, but if not, you’ll need to buy and install one. It prevents unnecessary filling of the water heater with antifreeze.

  • Tank Cleaning Wand

If your RV doesn’t have a built-in tank cleaning system, a tank cleaning wand ensures your holding tanks are spotless before the winter nap.

These materials will be your trusty companions as you safeguard your RV against the winter’s icy grip. Let’s move on to the next step – preparing the water system.

1. Preparing the Water System

Now that you’ve gathered your winterization materials, it’s time to prepare your camper’s water system. Here are the straightforward steps to ensure that your camper can survive the cold.

  •  Remove Inline Water Filters: Before you start the winterization, take out any inline water filters in your system. This ensures a clean start, and it’s an excellent time to replace expired filters.
  • Drain and Flush Holding Tanks: Head to a dump station or your campground’s sewer hookup to empty your black and gray tanks. Let the hose linger a bit longer to ensure a thorough drain. If your RV lacks a built-in flushing system, use your trusty tank cleaning wand for a spotless finish.
  • Drain the Water Heater Tank: Switch off the water heater before draining. Open the pressure relief valve and remove the drain plug. Ensure the tank cools down before proceeding.
  • Open All Faucets and Remove Drain Plugs: Let the water flow! Open all hot and cold faucets, including the toilet valve and outside shower. Locate and open the low point water drain lines. Use the water pump to assist in draining, but turn it off once the system is water-free to prevent pump damage.
  • Close Faucets and Replace Drain Plugs: Don’t forget this crucial step! Close all faucets and replace drain plugs once the water has fully drained.

2. Bypassing the Water Heater

At this point, your water system is prepared, you have to make sure your water heater gets a winter break without unnecessary exposure to antifreeze. Bypassing the water heater is a crucial step that saves you from wasting gallons of antifreeze.

Some RVs come equipped with a built-in water heater bypass kit. Check your RV’s manual or inspect the water heater system to see if you already have this feature. If your camper trailer manufacturer provides this convenience, you can move on to the next step.

For those without a built-in bypass kit, don’t worry – installing one is a manageable task. Purchase a water heater bypass kit from your local RV manufacturer or online. Follow the kit’s instructions to connect the bypass valve. This setup ensures that antifreeze doesn’t flow into the water heater, saving you precious gallons.

Once installed, double-check that the water heater bypass system is working correctly. Ensure that the valve is set to bypass, preventing antifreeze from entering the water heater.

3. Adding Antifreeze

With the water heater safely bypassed, it’s time to introduce the protective layer that will keep your camper’s plumbing system safe from the winter chill – the non-toxic RV antifreeze. Here is what you need to do now for winterization of your camper.

Find the water pump in your RV. This may require consulting your RV’s manual to identify its exact location. Once located, access the water pump. This may involve removing a panel or accessing a compartment, depending on your RV’s design.

If you have a water pump converter kit, connect it to the water pump. This kit allows you to draw antifreeze directly into the plumbing system. In the absence of a converter kit, you can disconnect one of the water lines and place it into a container of antifreeze. Ensure the container is positioned securely and won’t tip over during the process.

Turn on the water pump to initiate the flow of antifreeze into your RV’s plumbing system. Starting with the faucets closest to the water pump, open both hot and cold faucets. Allow the antifreeze to flow until you see a steady stream coming out. Repeat this process for all faucets, including the shower, bathroom, and kitchen sinks.

Flush the toilet until you see the distinctive pink color of the antifreeze. If your RV is equipped with additional water-based appliances, such as an ice maker or washing machine, consult your owner’s manual for specific instructions on winterizing these components. Keep a close eye on the expelled liquid. The pink color indicates the presence of antifreeze, assuring you that the entire system is protected.

Depending on the size of your RV and plumbing system, you may need more than 2-3 gallons of antifreeze. Be prepared to repeat the process until all lines are filled with the protective solution.

Once all faucets and appliances have been treated with antifreeze, turn off the water pump and you are good to move on.

5. Battery Care

Your camper’s battery is a powerhouse that keeps things running smoothly, and it needs a bit of attention before settling into winter hibernation. To move further in your wintirazation process, start by disconnecting the battery to prevent any unintentional power drain during the winter months.

Inspect the battery terminals for any corrosion. Use a battery terminal brush or a mixture of baking soda and water to clean off any buildup. This ensures a good connection.

If possible, charge the battery before storing your camper. A fully charged battery is better equipped to handle the colder temperatures and will be ready to go when you hit the road again.

If you’re storing the battery separately, find a cool, dry place. Avoid extreme temperatures, as both extreme heat and cold can affect the battery’s performance. Consider using a battery tender or maintainer to provide a low and steady charge.

Check the battery cables for any signs of wear or damage. If you notice any issues, address them before storing the battery. If possible, store the battery on a piece of wood or another insulating material. This helps prevent the cold ground from affecting the battery’s performance.

Periodically check the battery throughout the winter and ensure it stays charged, and there are no signs of corrosion or damage.

6. Exterior Protection

Now that you’ve tended to the important components inside your camper, let’s shift our focus to the exterior. Protecting the outer shell from winter’s harsh elements is crucial for maintaining your RV’s integrity.

  • Clean Thoroughly: Begin by giving your camper a thorough wash. Remove any dirt, grime, or road salt accumulated during your travels. This is especially important for preventing corrosion.
  • Inspect Seals and Caulking: Check all exterior seams, seals, and caulking for signs of wear or damage. Replace any cracked caulking to prevent water infiltration. A watertight seal is your first line of defense against winter weather.
  • Cover Vents and Openings: Cover external vents, including those for the refrigerator and furnace, with vent covers. This prevents pests from making a cozy home inside and protects against winter drafts.
  • Shield Tires: Invest in tire covers to protect your tires from prolonged exposure to the elements. This prevents cracking and maintains tire integrity, ensuring they’re ready for your next adventure.
  • Use an RV Cover: If storing your camper outdoors, consider investing in a quality RV cover. Choose one designed for winter use that provides adequate protection against snow, ice, and UV rays.
  • Lift the camper: If possible, park your camper on blocks or leveling jacks. This helps relieve pressure on the tires and prevents flat spots from forming during extended periods of inactivity.
  • Secure Window Protection: Close all windows and blinds securely to prevent cold drafts. For an extra layer of insulation, you can use thermal curtains or window insulator kits.
  • Inspect Roof and Seams:  Carefully inspect the roof for any damage or potential leaks. Repair any issues promptly, and consider applying a protective roof sealant if recommended by your camper trailer manufacturer.
  • Remove Propane Tanks: If you’re storing your camper for an extended period, consider removing propane tanks and storing them in a cool, dry place. This precaution minimizes the risk of gas-related issues.
  • Check Awning: If your camper has an awning, inspect it for any damage. Clean and dry it thoroughly before rolling it up for storage. Consider using an awning cover for added protection.

7. Interior Maintenance

This is the time to turn your attention to the cozy heaven inside your camper. Proper interior maintenance ensures a comfortable and well-preserved living space during the winter months. You need to start by giving the interior a thorough cleaning. Vacuum carpets, wipe down surfaces, and clean upholstery. A clean interior minimizes the chances of mold and unpleasant odors.

Empty your RV of any perishable food items. Even non-perishables like canned goods can be affected by extreme temperatures, so it’s best to store them elsewhere. Check the seals around windows and doors for any gaps or wear. Replace any damaged seals to keep the cold air out and maintain a cozy atmosphere inside.

Place moisture absorbers in various areas of the camper to prevent the buildup of condensation. If possible, prop up cushions and mattresses slightly to allow air circulation to prevent moisture from getting trapped and causing unpleasant odors.

Consider using an RV-specific space heater with safety features to maintain a consistent interior temperature. This not only keeps you comfortable but also protects sensitive electronics from extreme cold.

Pour a small amount of RV antifreeze down each drain to prevent any remaining water in the P-traps from freezing and causing damage.

Lock away any valuables or items that could be damaged during the winter months. Also, make sure that smoke detectors and carbon monoxide detectors are in working order. Replace batteries if needed. Safety should always be a top priority.

Crack open roof vents or windows slightly to allow for ventilation. This helps reduce the likelihood of a stale or musty smell developing inside your camper. If your RV uses propane for heating, cooking, or other appliances, ensure that the propane system is functioning correctly. Check for leaks and have any issues addressed promptly.

Consider using curtains or blinds to shield the interior from direct sunlight to prevent fading of upholstery and interior surfaces.

8. Interior Clean-Up

So, the last step of your campe winterization process is to clean up your interior. You can call this step an adon of the previous step where we worked on maintenance of our camper’s interior.
