Don't forget to winterize your RV!

As the colder months approach, it is important to properly winterize your RV to protect it from the harsh weather and ensure it is ready for use when the warmer seasons return. The following guide will help ensure you’re ready for that spring camping trip that’s only a few months away. For those of us short on time or if need help getting your rig ready for storage, we recommend Grant RV’s Service & Repair Winter-Ready Package.

  1. Clean and dry the interior. Before winterizing your RV, it is important to thoroughly clean and dry the interior. This includes vacuuming, dusting, and wiping down surfaces. If there is any standing water or moisture, be sure to dry it completely to prevent mold and mildew from forming.

  2. Disconnect the utilities. If your RV is not connected to a full-time power source, you will need to disconnect the utilities before winterizing. This includes the water, electricity, and gas. Turn off the main water valve and drain the water from the lines by flushing the toilet and running the faucets until they run dry. Disconnect the electricity by unplugging the RV from the power source and turning off the main breaker. If your RV is equipped with a propane tank, turn off the gas and close the valve.

  3. Winterize the plumbing. To prevent damage to the plumbing system, it is essential to winterize it properly. Start by draining the water heater and water pump. Then, locate the water intake valve and use a blowout plug or a compressor to blow out the water in the lines. You can also use non-toxic RV antifreeze to protect the plumbing. Pour a gallon of antifreeze into the freshwater tank and run it through the lines by flushing the toilet and running the faucets until you see pink water. Be sure to also drain the sewage tanks and apply a holding tank treatment to prevent odors and clogs.

  4. Protect the exterior. It is important to protect the exterior of your RV from the elements during the winter months. This includes covering the windows and sealing any cracks or gaps to prevent drafts. Use a high-quality RV cover to protect the exterior from snow, ice, and wind. Be sure to also remove any debris or leaves from the roof to prevent water damage.

  5. Store your RV properly. If you plan to store your RV for an extended period of time, it is important to find a safe and secure storage location. Choose a covered or indoor storage facility to protect your RV from the elements. If storing your RV outside, invest in quality tire covers and blocks to support the weight and prevent flat spots from forming. It is also a good idea to invest in a battery tender to keep the battery charged and prevent it from dying.

  6. Perform maintenance checks. Before winterizing your RV, it is a good idea to perform a thorough maintenance check to ensure everything is in good working order. This includes checking the brakes, tires, and engine. Be sure to also change the oil and check the fluid levels. If any repairs or maintenance is needed, it is best to take care of it before winterizing to avoid any issues during the colder months.

Bonus Tip – Check for any liquids in the pantry or storage that may freeze and crack, or worse yet, explode when they thaw like carbonated beverages.

By following these steps, you can properly winterize your RV and protect it from the harsh winter weather. Proper winterization not only helps to preserve the condition of your RV, but it also ensures it is ready for use when the warmer seasons return.
