Step 1: Drain All Water Systems

Water left in your camper’s pipes, tanks, or water heater can freeze, expand, and potentially crack or damage them. Here’s how to clear out your water systems:

1. Turn off the Water Heater and Pump: Make sure the water heater is off and cooled down to avoid any scalding accidents.
2. Drain the Freshwater Tank: Open the freshwater drain and let it empty completely.
3. Drain the Water Heater: Open the drain plug and relief valve on the water heater. Make sure to let it fully drain.
4. Open Faucets and Drain Lines: Open all faucets, including hot and cold, and flush any water out of the lines.
5. Use Compressed Air (Optional): You can blow out the lines with compressed air to make sure no water is left. Attach the air compressor to the city water inlet with an adapter and blow out the lines.

Step 2: Add RV Antifreeze to the Plumbing System

Once the water is drained, adding non-toxic RV antifreeze to the system is a vital step to protect your camper’s plumbing.

1. Bypass the Water Heater: If your camper has a water heater bypass valve, use it. This prevents antifreeze from filling the water heater and wasting it.
2. Pump Antifreeze into the System: Use your water pump or a hand pump to distribute antifreeze throughout the lines. Open each faucet, shower, and toilet until you see pink antifreeze coming through.
3. Pour Antifreeze into Drains: Don’t forget to add antifreeze to all drains and the toilet. This helps protect the p-traps and prevents sewer gasses from entering the camper.

Step 3: Protect the Exterior

Your camper’s exterior is exposed to harsh winter conditions, so protecting it from the elements can save you from potential damage.

1. Clean and Inspect: Give your camper a thorough wash to remove any dirt or debris. Inspect seals around windows, doors, and the roof for any cracks or damage.
2. Wax the Exterior: A fresh coat of wax provides a protective layer against moisture and keeps your camper looking good.
3. Cover Your Camper: If possible, invest in a high-quality camper cover to shield it from snow, ice, and debris. Avoid using tarps, as they can trap moisture and damage the exterior.

Step 4: Care for the Interior

Cold temperatures and prolonged storage can lead to issues inside your camper as well. Taking a few steps to prep the interior will keep it fresh and ready for spring.

1. Clean Thoroughly: Remove all food, clean the fridge and freezer, and leave the doors slightly ajar to prevent mold.
2. Protect Against Pests: Use pest repellents and seal any small openings where rodents might enter. Rodents love to chew on wires and upholstery, so keep them out!
3. Ventilation: Leave roof vents cracked to allow airflow. Vent covers are a good idea as they prevent moisture buildup while keeping snow out.

Step 5: Prepare the Battery and Electrical Systems

Cold weather can be tough on batteries and other electronics. Follow these steps to ensure your camper’s electrical system is winter-ready.

1. Disconnect the Battery: Cold temperatures can drain batteries quickly. Disconnect and store them in a cool, dry place if you’re not using a trickle charger.
2. Use a Battery Tender: If you leave the battery connected, consider using a battery tender to keep it charged and ready to go.
3. Inspect Wiring: Look over your electrical wiring and make sure all connections are secure. This can prevent unwanted surprises next season.

Step 6: Take Care of Tires and Stabilize the Camper

If your camper will be sitting in one place for the winter, take a few steps to ensure your tires and leveling system are protected.

1. Inflate Tires to Proper Pressure: Tires can lose air over time, so inflate them to the recommended pressure.
2. Use Tire Covers: These will protect tires from UV exposure, which can cause cracking even during winter.
3. Use Stabilizers: Make sure your camper is level and stable. Stabilizers or leveling blocks are helpful to keep it from shifting during winter storms.

Step 7: Check for Insurance and Maintenance Needs

Before you say goodbye to your camper for the season, it’s a good idea to review your insurance coverage and any pending maintenance.

1. Review Insurance: Make sure your insurance covers storage-related issues or damage, so you’re protected during the off-season.
2. Schedule Spring Maintenance: Schedule any necessary maintenance for early spring, like inspecting the roof, seals, and plumbing, so your camper is road-ready once winter is over.

Final Thoughts

Winterizing your camper might take a bit of time, but it’s worth every minute. Protecting your camper from freezing temperatures, moisture, and potential pest damage will ensure it’s in great shape for your next adventure. Following these steps can save you time, money, and a lot of frustration down the road. Happy winterizing!
