How do I properly winterize and store my trailer for the winter?

Please take a moment to watch the video below for step-by-step guidance, or follow the step-by-step written directions.

If you need additional help, our After Sales team at Escape Trailer will be happy to assist you. You can submit a support ticket using this form. 

1. Take Care of the Batteries

  • Lead-acid batteries

    • If the trailer is plugged into power, leave the batteries installed.

    • Turn the battery disconnect switch OFF to prevent parasitic drain.

    • Make sure batteries are fully charged before storage.

    • If the trailer is not plugged in, check the battery charge periodically so it doesn’t drop too low (which can risk freezing).

  • Lithium batteries

    • Remove the batteries from the trailer.

    • Store them indoors in a cool, dry place (like a garage).

    • Charge them to about 75–80% before storage.

    • Avoid storing lithium batteries at 100% charge for long periods.

 

2. Drain and Winterize the Water System (Critical Step)

  • Drain all water from:

    • Fresh water tank

    • Grey and black holding tanks

    • Water heater

    • All water lines

  • Winterize the system:

    • Add RV antifreeze into all water lines and traps.

    • Make sure antifreeze reaches:

      • Faucets (open one at a time)

      • Toilet valve

      • Outside shower

    • Do NOT put antifreeze in the water heater.

  • Blow out water lines:

    • Use an air compressor.

    • Open each faucet one at a time.

    • Do not exceed 40 PSI.

    • A water pressure regulator can help control air pressure.

 

3. Shut Down the Propane System

  • Turn off propane valves at the tanks.

  • Ensure all propane appliances are switched off.

  • Close tank valves securely.

  • (Optional) Remove propane tanks for separate storage if desired.

 

4. Clean Out the Interior

  • Remove all food from the trailer (even sealed items).

  • Clean out cabinets and storage areas.

  • Prop the refrigerator door open:

    • Prevents mold and odors.

    • Place a towel so the door can’t accidentally close.

 

5. Control Moisture Inside the Trailer

  • Place moisture absorbers throughout the RV.

  • Check and replace them during the winter as needed.

  • If you have power available:

    • Use a low-wattage air circulator or fan to keep air moving.

  • Leave cabinet doors open to improve airflow.

 

6. Exterior Preparation

  • Extend the awning fully.

  • Clean it thoroughly.

  • Let it dry completely before rolling it up.

    • A dirty or wet awning stored all winter can grow mold and become stained.

 

7. Inspect and Protect Seals

  • Check caulking around:

    • Windows

    • Roof vents

    • Any exterior openings or seams

  • Repair any cracks or gaps to prevent leaks during winter.

 

8. Consider an RV Cover (If Needed)

  • If your trailer is not under a roof, consider using an RV cover.

  • Note: Covers are not fully waterproof but help protect from:

    • Sun damage

    • Bird droppings

    • Tree sap

    • Debris
