Winterizing your motorhome is crucial to prevent costly damage and ensure it's ready for adventures when spring arrives. Neglecting proper winterization can lead to frozen pipes, mold growth, and other issues that could significantly impact your RV's lifespan and your wallet. This comprehensive guide will provide you with expert tips and tricks to protect your investment and keep your motorhome in top condition throughout the cold winter months.
How Do I Prepare My Motorhome for Winter Storage?
Preparing your motorhome for winter storage is a multi-step process. It's not just about parking it in a safe spot; it's about proactively protecting it from the elements and potential damage. Here's a detailed breakdown:
1. Cleaning and Preparation: Laying the Foundation
Before storing your motorhome, give it a thorough cleaning, inside and out. Remove all trash, food items, and personal belongings. Clean and dry all surfaces to prevent mold and mildew growth. This includes wiping down cabinets, countertops, and the interior walls. For the exterior, wash and wax the RV to protect the paint from the harsh winter elements.
2. Protecting the Interior: Preventing Damage
- Ventilation: Ensure adequate ventilation to prevent moisture buildup. Slightly open windows or use dehumidifiers (with proper ventilation) to maintain air circulation.
- Furniture Protection: Cover upholstered furniture with protective covers to prevent dust and damage.
- Electronics: Disconnect and store batteries properly to avoid damage from freezing temperatures. Consult your owner's manual for specific instructions.
3. Winterizing the Plumbing System: Preventing Frozen Pipes
This is arguably the most critical step. Frozen pipes can cause significant damage and costly repairs. The process generally involves:
- Draining Water Tanks and Lines: Completely drain all freshwater tanks, hot water heater, and plumbing lines. Use compressed air to blow out any remaining water.
- Adding RV Antifreeze: Pour RV antifreeze (propylene glycol-based) into all drains, low points, and faucets. This prevents freezing and protects your plumbing system.
- Winterizing the Toilet: Follow the manufacturer's instructions for winterizing your toilet, which may involve adding antifreeze to the bowl and tank.
4. Protecting Against Pests: Keeping Critters Out
Rodents and insects can cause significant damage during winter storage. Take these preventive measures:
- Seal Entry Points: Inspect your motorhome thoroughly for any cracks or openings and seal them with caulk or sealant.
- Mothballs or Repellents: Place mothballs or rodent repellent inside the motorhome to deter pests. Be sure to choose pet-safe options if you have pets.
- Storage Location: Choose a clean, dry storage facility and consider placing mothballs near the tires to deter mice and other rodents.
5. Choosing the Right Storage Location: Safe and Secure
Where you store your motorhome significantly impacts its condition during winter. Consider these factors:
- Indoor vs. Outdoor Storage: Indoor storage offers the best protection from the elements. Outdoor storage requires more diligent preparation and winterization.
- Security: Choose a secure location with good lighting and surveillance to deter theft and vandalism.
- Accessibility: Ensure easy access to your motorhome if you need to check on it during the winter.
6. Battery Maintenance: Keeping the Power Source Alive
- Disconnect Batteries: Disconnect the batteries to prevent drain and potential damage.
- Trickle Charger: Use a trickle charger to maintain a slight charge in the batteries to prevent them from becoming completely discharged.
- Storage: Store the batteries in a cool, dry location away from extreme temperatures.
7. Tire Care: Protecting Your Wheels
- Proper Inflation: Inflate tires to the recommended pressure, which may slightly increase for winter storage.
- Support: Use tire supports or blocks to prevent flat spotting of the tires over extended periods.
- Rotation: If storing for a long period, consider rotating your tires to distribute the pressure more evenly.
8. What About LPG (Propane)?
Make sure your propane tanks are turned off and disconnected. If you have a low-level warning device, you'll want to disable that as well to prevent false alarms during storage.
How Long Can a Motorhome Sit Without Being Driven?
The length of time a motorhome can sit without being driven depends on several factors, including the quality of your pre-storage maintenance, the storage conditions, and the age/condition of the vehicle. However, with proper preparation and storage, you can typically store your motorhome for several months without issues. Regular checks during storage are recommended, particularly in less-than-ideal storage conditions.
What Happens If You Don't Winterize Your Motorhome?
Failing to winterize your motorhome exposes it to significant risks, including:
- Frozen and burst pipes: This can result in substantial water damage, costly repairs, and even replacement of parts of the plumbing system.
- Mold and mildew growth: Moisture trapped inside the RV can encourage the growth of mold and mildew, causing health issues and leading to unpleasant odors and significant cleaning challenges.
- Damage to appliances: Freezing temperatures can damage appliances like refrigerators, water heaters, and even the toilet system.
- Damage to interior components: Extreme temperatures can cause damage to seals, wood, and other materials inside the motorhome.
By carefully following these winter storage tips, you can significantly reduce the risks associated with storing your motorhome during the cold winter months. Remember, proper preparation is key to protecting your investment and ensuring many years of enjoyable RV travel.
