How to Save Money on Fuel When Travelling with a Caravan or Motorhome

With fuel prices constantly changing, many travellers are looking for ways to make their caravanning adventures more affordable. The good news? A few simple adjustments can significantly improve fuel efficiency and help you spend less at the bowser and more on making memories.

At Adelaide RV, we’re passionate about helping Australians get out and explore. Here are our top tips for reducing fuel consumption when travelling with a caravan or motorhome.

1. Choose the Right RV for Your Travel Style

One of the biggest factors affecting fuel consumption is what you’re travelling in.

Motorhomes are often one of the most fuel-efficient ways to travel, with many modern models achieving around 9–10 litres per 100 kilometres. Pop top caravans can also be a great option, thanks to their lighter weight and lower profile, which helps reduce wind resistance.

Full-size caravans offer more space and comfort, but the added weight and larger surface area generally require more fuel to tow.

If fuel economy is high on your priority list, it’s worth considering how often you’ll travel and what type of setup best suits your adventures.

2. Slow Down and Enjoy the Journey

When towing a caravan, speed has a major impact on fuel consumption.

While it’s tempting to push on and get to your destination sooner, travelling at higher speeds forces your vehicle to work much harder against wind resistance.

For many travellers, the sweet spot sits around 95 km/h. At this speed, you’re still keeping up with traffic while allowing your vehicle to operate more efficiently.

Using cruise control where appropriate can also help maintain a consistent speed and improve fuel economy over long distances.

3. Check Your Tyre Pressures

Tyre pressures are one of the most overlooked factors when it comes to fuel efficiency.

Underinflated tyres create more rolling resistance, meaning your vehicle needs to work harder and burn more fuel.

Before every trip:

• Check your vehicle tyre pressures.
• Check your caravan tyre pressures.
• Follow the manufacturer’s recommended specifications.

It’s also a good idea to recheck pressures after the first hour of travel, particularly if you’re stopping for fuel or a coffee break.

Proper tyre maintenance not only improves fuel economy but also enhances safety and tyre longevity.

4. Pack Smarter and Travel Lighter

Modern caravans offer plenty of storage space, but that doesn’t mean every compartment needs to be full.

Every kilogram you carry requires energy to move. The heavier your caravan, the more fuel your tow vehicle will use.

Before you leave, ask yourself:

• Do I really need this item?
• Will I actually use it on this trip?
• Is there a lighter alternative?

Travelling with only the essentials can make a noticeable difference to your fuel consumption over longer journeys.

5. Avoid Travelling with Full Water Tanks

Water is surprisingly heavy.

Many caravans carry around 200 litres of fresh water, which adds approximately 200 kilograms of weight before you’ve packed anything else.

If you’re travelling between caravan parks or destinations where water is readily available, consider carrying only enough water for emergencies and basic use during transit.

Reducing water weight can be one of the easiest ways to improve towing efficiency and lower fuel costs.

6. Improve Aerodynamics

Aerodynamics play a significant role in fuel consumption.

Lower-profile caravans, such as pop tops, naturally create less drag than full-height caravans. However, your tow vehicle also contributes to overall aerodynamic efficiency.

Consider removing:

• Roof racks you won’t use.
• Unnecessary storage pods.
• Extra accessories mounted externally.
• Equipment that adds wind resistance.

The cleaner and more streamlined your setup, the less fuel you’ll use.

7. Drive Smoothly and Consistently

Aggressive driving habits can dramatically increase fuel consumption.

Frequent acceleration, heavy braking, and rapid overtaking all require additional fuel.

Instead:

• Accelerate gradually.
• Maintain a consistent speed.
• Use cruise control when safe to do so.
• Anticipate traffic conditions ahead.
• Let momentum work in your favour.

A smoother driving style not only saves fuel but also makes for a more relaxing and enjoyable journey.

8. Consider Travelling Closer to Home

One of the simplest ways to reduce travel costs is to shorten the distance.

South Australia is full of incredible destinations that don’t require days on the road. A weekend on the Fleurieu Peninsula, for example, may use significantly less fuel than a longer trip into the Flinders Ranges.

Sometimes the best adventures are closer than you think.

Start Travelling More for Less

Reducing fuel costs doesn’t mean giving up the freedom of caravanning. By choosing the right RV, maintaining your vehicle, travelling lighter, and adopting fuel-efficient driving habits, you can spend less on fuel and more on enjoying the journey.
