Winterizing your RV or camper is an essential step in protecting your investment from the harsh cold of the winter months. However, now that spring is on the horizon, it’s time to start thinking about how to dewinterize your camper or RV. Dewinterizing is crucial to ensure your vehicle is ready for the upcoming season, and neglecting it can lead to unwanted consequences. In this comprehensive guide, we will take you through the process of dewinterizing your RV step by step, from when to start to the essential inspections and maintenance tasks to perform. Let’s dive into how to de-winterize your RV and get it ready for your next adventure.
When Should You Dewinterize Your Camper?
The timing of your dewinterization is crucial. You don’t want to start too early, as cold snaps can still occur, but waiting too long can lead to issues when you’re finally ready to hit the road. As a rule of thumb, consider dewinterizing your RV or camper when the weather consistently stays above freezing. Waiting too long can lead to plumbing system damage and other problems.
Dewinterizing your RV in a timely manner ensures that you can enjoy your vehicle to the fullest without any unpleasant surprises. Neglecting this step could result in costly repairs and inconvenience down the line.
Basic Inspection and Safety Checks
Before you embark on your first spring adventure, it’s essential to conduct a series of basic inspection and safety checks to ensure your RV or camper is in good condition. Here are ten key areas to focus on:
- Propane System: Ensure there are no leaks, and all connections are secure.
- Electrical System: Test all outlets, switches, and appliances.
- LP Gas Detector: Check the LP gas detector for proper functioning.
- Fire Extinguisher: Verify it’s charged and easily accessible.
- Smoke and Carbon Monoxide Detectors: Replace batteries and test them.
- Brakes and Lights: Inspect the brakes and lights to ensure they are working correctly.
- Wheel Bearings: Grease the wheel bearings for smoother travel.
- Awnings: Examine awnings for tears or damage.
- Slide-Outs: Check the slide-outs for proper operation and seals.
- Emergency Kit: Ensure you have a well-stocked emergency kit, including first-aid supplies.
By performing these checks, you can travel with peace of mind, knowing that your RV is safe and ready for the road.
Check Your RV Tires
Your RV’s tires are the foundation of your journey. Proper tire maintenance is crucial for both safety and performance. Start by checking the tire pressure and ensuring it matches the manufacturer’s recommendations. Inspect the tread depth, and if it’s below the recommended level, consider replacing the tires. Also, remember to rotate your tires regularly to ensure even wear, especially if you plan on embarking on long trips.
Check Your RV’s Battery Condition
Your RV typically has two types of batteries: house batteries and starting batteries. Both require regular checks to ensure they are in good condition. House batteries power appliances and lights, while the starting battery, as the name suggests, starts the engine.
Inspect the batteries for any signs of corrosion, and make sure the terminals are clean and well-connected. Check the water level in house batteries and top them off with distilled water if necessary. Additionally, ensure your batteries are charged and consider investing in a battery maintainer to extend their life.
Examine Your RV Generator or RV Solar Components
If your RV has a generator or solar components, don’t forget to give them a thorough examination. Start by checking the oil level and making sure it’s at the right level. Test the generator to ensure it starts and runs smoothly. For solar components, inspect the panels for any damage, and clean them to ensure maximum efficiency.
Antifreeze Your Plumbing System
One of the most critical steps in dewinterizing your RV is ensuring your plumbing system is free from any traces of antifreeze. Failing to do this can lead to contamination of your water supply. Here’s how to safely remove antifreeze from your plumbing system:
- Flush the System: Connect your RV to a freshwater source and open all faucets, including the toilet and outdoor shower. Run the water until there is no trace of antifreeze.
- Water Heater: Make sure to drain and flush the water heater separately to remove any remaining antifreeze.
- Water Lines: To be extra thorough, you can blow out the water lines using compressed air, which ensures there’s no residual antifreeze.
Sanitize and Flush Your Water System
Another step to de-winterize your camper or RV is, once the antifreeze is removed, it’s time to sanitize and flush your water system to ensure it’s clean and safe for use. Follow these steps:
- Sanitize the Water Tank: Add a mixture of water and RV-safe sanitizer to your freshwater tank and let it sit for a few hours. Then, flush it out thoroughly.
- Flush Water Lines: Run water through all faucets until the sanitizer smell is gone.
- Water Heater: After sanitizing, ensure you flush the water heater again to remove any residual sanitizer.
By following these steps, you’ll have a clean and safe water supply for your RV adventures.

Inspect Your RV’s Interior and Restock the Essentials
A thorough interior inspection is crucial for ensuring your comfort on the road in the list of tasks when it comes to dewinterize your camper. Start with a top-to-bottom cleaning of your RV’s interior:
Clean the Interior from Ceiling to Floor
Begin by cleaning every nook and cranny of your RV’s interior. Dust, vacuum, and wipe down all surfaces. Pay special attention to your kitchen and bathroom, as these areas are prone to mold and mildew growth during winter storage.
Drain Dehumidifiers
If you use dehumidifiers to control moisture during winter storage, be sure to drain and clean them. Failure to do so can lead to unpleasant odors and decreased efficiency.
Check Cabinets and Under Sinks for Pests
Inspect all cabinets and spaces under sinks for signs of pests. Mice and insects can wreak havoc on your RV, so be vigilant.
Check the Water Filtration System
Examine the water filtration system to ensure it’s functioning correctly. Replace filters if necessary to maintain water quality.
Check Your Safety Devices and Alarms
Test all safety devices and alarms, such as smoke detectors and carbon monoxide detectors, to ensure they are operational. Replace batteries if needed.
Inspect Your RV’s Exterior
A well-maintained exterior is not only visually appealing but also ensures the safety and longevity of your RV. Here are some essential steps for exterior maintenance:
Give the Exterior a Good Wash and Wax
Start by washing your RV’s exterior to remove dirt, grime, and any residue from the winter months. Follow up with a protective wax coating to keep your RV looking its best and protect it from the elements.
Look for any Cracks, Cuts, or Holes on Your Roof
A thorough roof inspection is vital to prevent water leaks. Check for any cracks, cuts, or holes in the roof material and seal them to prevent water damage.
Inspect Vent Caps
Examine all vent caps on the roof for damage or cracks. Replace any damaged vent caps to prevent water infiltration.
Give Your Solar Panels a Good Cleaning
If your RV is equipped with solar panels, clean them to ensure maximum energy production. Dirty panels can lead to reduced efficiency, which is not ideal when you’re on the road.
Check for Damage to any Plumbing, Wiring, or Gas Lines
Inspect all plumbing, wiring, and gas lines to ensure they are free from damage and leaks. Replace any damaged components promptly to avoid potential hazards.
