Step 3: Charge Or Replace Your RV Batteries

Step 4: Flush Your Water System

If you are living in an area where the temperature consistently drops below freezing, it is important to take steps to protect your camper trailer from winter damage. One of the most important things you can do is flush your water system.

By flushing out all of the silt and sediment that has built up over the winter, you will help to prevent your trailer from becoming icy and slippery when it snows.

  • First of all, make chlorine solution. Then mix one cup of liquid household chlorine bleach in every 20 to 30 gallons of water.
  • Flush the solution in the water system and let it be there for a few hours
  • After waiting for the required time, now it’s time to drain and flush it. Now drain out the chlorine solution and fill the tank with freshwater.
  • open all the hot water faucets and let the water run until you don’t feel a chlorine smell. It will also help to bleed air from RV water lines easily.

In addition, make sure all of your windows are sealed tight and check for any leaks around the seals. Finally, keep your propane tanks topped off and ensure that all electrical appliances are winterized as well.

Step 7: Clean Your Camper’s Interior

If you have a camper trailer, there is a good chance that you will need to clean it at some point during the winter. This can be done in a few easy steps.

  1. Make sure that all of your windows and doors are closed tight. This will keep the interior of your trailer warm and dry.
  2. Get a vacuum cleaner with a hose attachment and clean all of the dirt and snow from inside your camper trailer. You can also use a broom to sweep any loose snow or dirt off the floor.
  3. Get some disinfectant wipes or soap and wash all of the surfaces inside your camper trailer, including the walls, ceiling, windows, and doors.
  4. Finally, vacuum all of the surfaces clean.

Step 8: Check For Leaky Pipes

  • Check for water leaks by turning off all the taps and checking for water running everywhere. If there are any leaks, fix them immediately by replacing damaged or worn parts with new ones.
  • Clear out any snow and ice from around the exterior of the camper trailer using a shovel or a snowblower. This will help keep moisture out and make it easier to see any potential water leaks.
  • Check for frozen pipes by inserting a thin, flexible tube into the cold water supply line and checking for leaks. If there are any leaks, fix them immediately by replacing damaged or worn parts with new ones.

Step 9: Inspect The Propane System

One of the first things you should do when de-winterizing your camper trailer is inspect the propane system. Make sure there are no leaks, that all hoses and connections are secure, and that the propane tanks are full. If there are any problems with the propane system, you’ll need to repair or replace them before you can use your trailer in the spring.
