6 Essential Caravan Maintenance Tips to Keep Your Van Adventure Ready

At Adelaide RV, we believe that every journey should be safe, smooth, and stress-free. While our expert team takes care of your scheduled annual servicing, there are simple steps you can take in between visits to keep your caravan in top condition.

In this guide, Aaron, one of our service technicians, shares six easy caravan maintenance checks that every owner can do at home. These quick inspections and simple tasks will save you headaches on the road and ensure your van is always ready for your next adventure.

1. Check Your Wheels and Tyres

Your wheels are the foundation of safe towing, so make them a priority. Before heading out:

• Visual Inspection: Look over your rims and tyres for damage, cracks, gouges, or uneven wear.

• Tread Depth: Ensure there’s plenty of tread left for safe grip.

• Wheel Nuts: Tighten using a wheel brace (or torque wrench if you have one). Follow the star pattern for even pressure. At Adelaide RV, we torque to factory specifications of 135 Nm.

• Tyre Pressure: Inflate according to your caravan compliance plate, or generally 45–50 PSI for large off-road tyres.

A few minutes of attention here prevents costly issues and improves towing confidence.

2. Keep Locks and Drop-Down Legs Lubricated

Caravans travel through dust, dirt, and weather – all of which can cause locks, drop-down legs, and key barrels to seize up. Aaron recommends:

• Using a quality silicone spray to keep locks smooth and dust-free.

• Graphite powder as an alternative (but don’t mix the two).

• Avoiding wet sprays like WD-40, as they attract dirt.

Keeping everything lubricated makes setup and pack-down easier and protects your fittings long term.

3. Inspect Windows, Seals, and Struts

Your windows and seals keep the elements outside and comfort inside. Regular inspection prevents leaks and damage.

• Check that screws are tight and secure.

• Test latches, knobs, and blind mechanisms.

• Inspect window seals to ensure they are seated correctly and haven’t popped out.

This small step in your caravan maintenance routine keeps your van watertight and comfortable no matter the conditions.

4. Tighten Screws and Caravan Fixings

On the road, vibrations loosen screws and fittings over time. A simple walkaround with a screwdriver can save big repair bills later.

• Check cupboard doors, drawer runners, catches, and struts.

• For screws that continually work loose, apply Loctite or glue.

• If problems persist, replace with a larger gauge or slightly longer screw where possible.

By keeping everything tight, you protect both your caravan’s structure and your peace of mind.

5. Flush and Maintain Your Water Tanks

Clean water is essential for comfort and safety. Between trips:

• Freshwater Tanks: Add a sanitising solution through the fillers, fill the tank, slosh it around, and drain from the bottom outlet.

• Grey Water Tanks: Pour sanitiser down your sink and shower drains to break down grime, then flush with fresh water through the breather line (if your tank has one).

• Storage Tip: The debate as to whether it’s better to leave your water tanks empty, full, or partially filled, continues to this day. Aaron recommends emptying them, while in the past Jeb has said to keep them full, but drain and refill before a trip.

Clear tanks mean accurate readings and fresh water when you need it most.

6. Run Your Diesel Heater on High

If your van has a diesel heater, a little post-trip care will keep it reliable:

• After long trips, run the heater on its highest setting for a five minutes.

• This burns off carbon build-up and clears the system.

• It ensures easier startups and less smoke on your next journey.

It’s a quick win for comfort, especially in cooler climates.

Why Caravan Maintenance Matters

Caravanning is about freedom, comfort, and creating lasting memories. A little regular attention helps:

• Keep you safe on the road – by preventing tyre blowouts, loose fittings, or faulty locks.

• Save you money – catching small issues before they become expensive repairs.

• Extend your van’s life – so your caravan is ready for years of adventures.
