Motorhome Winterising

What do I need to consider when winterising my motorhome?

As the colder months approach, it's important to take steps to winterise your motorhome to protect it from potential damage and ensure its longevity.

Proper winterisation can help you avoid costly repairs and ensure your vehicle is ready for your next adventure when the weather warms up. Here's a checklist of considerations to keep in mind:

Preparing Your Motorhome

Prior to winterising, ensure that your motorhome is parked on level ground and that the vehicle is in gear. Release the handbrake to prevent it from becoming stuck. Begin the process by emptying the black, grey, and fresh water tanks to prevent freezing and potential damage to the plumbing system.

Leave cupboard doors open to allow air circulation and minimise moisture buildup. Empty the fridge and freezer of all contents and leave the doors open to prevent mould and odours.

Treat your water tanks with appropriate cleaning fluids to prevent the growth of bacteria and algae during storage. Open all taps and faucets to drain any remaining water from the lines. This helps prevent freezing and potential bursting of pipes.

Don't forget to treat locks and hinges with silicon spray to prevent rust and ensure they remain operational when you're ready to use your motorhome again.

Gas and Appliances

Shut off the gas supply to your motorhome to prevent leaks and ensure safety.

Battery and Electronics

Recharge the on-board battery every 4 to 6 weeks to maintain its health. Remove electronic devices to prevent damage from temperature fluctuations and potential pests.

Tyres, Fluids, and Exterior

Inflate the tyres to the correct pressure to prevent flat spots from forming during storage. Check the anti-freeze and oil levels to ensure proper engine protection. Clean both the interior and exterior of the vehicle thoroughly to remove dirt, debris, and potential contaminants.

Preventing Dampness

If you're not planning to use your motorhome during the winter months, remove the bedding to prevent moisture buildup and potential damage. Remove other textiles that may become damp and store them in a dry place. Consider using dehumidifying crystals inside the motorhome to absorb excess moisture and prevent mould growth.

Security Measures

Lastly, take measures to secure your motorhome against theft. This may include using wheel locks, alarms, or storing your motorhome in a secure location.

By following these considerations and properly winterising your motorhome, you can ensure that it remains in excellent condition throughout the colder months and is ready for your next adventure when the weather improves.
