How To Winterize Your RV

There are 5 main (easy) aspects of winterizing your RV, this is an easy job to do yourself, or you can hire someone if you don’t have the time.

Steps To Winterize Your RV

Drain the Water

One of the most important parts of winterizing your RV is making sure all of the water is out. When water freezes it will expand which can lead to busted and cracked pipes within your trailer, RV or fifth wheel.

You can get all of the water out of your RV by:

  1. Turning off your water pump and water heater and draining your rig completely.
  2. Run RV & Marine antifreeze through your system by pouring it down all of your drains. If you are deciding to use antifreeze, always remember that once your RV is in use again, you must flush your rig until all of the antifreeze is out of the system.

Get the Food Out

Something you may not think of within your RV that needs to be taken care of before storing it in winter temperatures is the dry food from your pantry. Although the cold temperatures will not necessarily affect the quality of your food, it has the potential to attract rodents and bugs to your camper. Moving food out of your camper will keep bugs and rodents away.

Keep Pests Out

Something else to check is to make sure there are no spaces for rodents to get into your rig to escape the cold. A rodent getting into your RV can lead to chewed wires, and will destroy parts of your rig. Attaching bug guards to the outside of your rig will also keep bugs away and keep all of your vents protected and secured.

Don’t Forget the Fridge

Another part of your rig that must be taken care of before storing your rig when it is cold outside and for long periods of time is your refrigerator. Make sure to completely empty your RV refrigerator and prop the doors open. Take the time to wipe up any excess water once the ice defrosts and prop the door open. Many RV shops will sell attachments that will keep your doors open while your rig is being winterized. Keeping your doors propped open will allow your fridge to air out and keep mold and mildew away.

Detach & Remove the Battery

Besides the steps mentioned above, another smart thing to do before you store your rig is to detach the battery and store it in a warm place. By leaving the battery attached you risk draining the battery or the freezing temperatures and ice damaging your battery. Simply detach your battery and store it inside or in a warm place so when you are ready for your next trip, you aren’t greeted by a completely dead battery.
