Preparing Your RV for Winter: Expert Tips for Cold-Weather Maintenance

As we head into fall, remember that winter looms over the horizon. It's crucial for RV owners to start thinking about winterizing their beloved mobile homes and travel trailers. Properly preparing your RV for the cold weather can save you from potential damage and costly repairs down the line. If you're unsure where to begin, fear not! This comprehensive guide will walk you through the essential steps to winterize your RV like a pro.


Step 1: Inspect Your RV's Exterior


RV Exterior Inspection

The first step in winterizing your RV is to thoroughly inspect the exterior. Check for any cracks, gaps or areas of wear and tear on the roof, windows, and seams. Sealing any potential entry points for moisture will help prevent leaks and water damage during the winter months. Take a look at the condition of your tires. If the DOT date, tread wear or sidewall breakdown indicates it might be time for replacement, take note so you have time to replace them in the Spring.


Step 2: Drain and Flush Water Systems


Before temperatures plummet, it's crucial to drain and flush all water systems in your RV. This includes the freshwater tank, water heater, and pipes. Failing to do so can result in frozen pipes and costly repairs. Don't forget to empty the black and grey holding tanks and add non-toxic antifreeze to prevent freezing. After winterizing the water pipes, find your low point drains (usually blue and red PEX tubing close together) and leave them open. Everyone has their preferences on how to winterize your water system, but the goal is to remove water that can expand in freezing conditions and crack fittings, pipes, and appliances.


Step 3: Protect Your Batteries


RV Battery Protection

Cold weather can be tough on RV batteries. To ensure they stay in good condition, remove them from the RV and store them in a cool, dry place if you cannot maintain a "trickle charge" throughout the cold months. Consider investing in a battery tender to maintain optimal battery health during the winter if you don't already have one. Regularly check the battery charge and top off the water level with distilled water if required. Many RV owners have converted to maintenance free batteries, like Lithium and LiFeSO4, that do not need water added. Remember, wet cell batteries will start to become irreparably damaged when allowed to drain down past 50% charge. Lithium batteries can be completely drained without becoming damaged.


Step 4: Check Heating Systems


If you plan to use your camper all year long, your RV's heating system will be your best friend when braving the cold. Before winter sets in, have a professional inspect and service your RV's furnace to ensure it's in proper working condition. Additionally, stock up on propane to keep your RV warm and cozy throughout the winter season.


Step 5: Seal Windows and Doors


Inspect all windows and doors for gaps or leaks that could let cold air in and warm air out. Applying weather stripping or utilizing draft stoppers can help maintain a comfortable temperature inside your RV and reduce energy costs.


Step 6: Prepare for Storage


If you won't be using your RV during the winter, it's crucial to prepare it for storage properly. Thoroughly clean the interior, remove any perishable items, and consider using moisture absorbers to prevent mold and mildew. Cover your RV with a breathable, weather-resistant cover to protect it from the elements, or find an RV storage facility that provides overhead coverage and maybe even power. These facilities can be pricy, but so can an early roof replacement.


By following these expert tips for winterizing your RV, you can ensure that your home on wheels stays in top shape throughout the cold winter months. Remember, proper maintenance now can save you from headaches and expenses later on. Stay warm, stay safe, and enjoy the beauty of winter adventures in your cozy, winter-ready RV!
