Towing a caravan is an exciting way to explore Australia, but getting your caravan weight right is crucial for safety, legality, and overall towing performance. Whether you’re a seasoned caravanner or just getting started, understanding caravan weights can help you avoid fines, prevent accidents, and ensure a smooth ride on the open road.
Why Caravan Weights Matter
1. Safety First
An overloaded caravan affects your towing stability, braking distance, and fuel efficiency. If your van is too heavy or incorrectly balanced, you risk swaying, tyre blowouts, or even jackknifing, which can be dangerous for you and other road users.
2. Avoid Fines and Insurance Issues
Did you know that exceeding your legal weight limit can result in hefty fines or even void your insurance? Authorities are cracking down on overweight caravans, and many insurance companies won’t cover you in an accident if your caravan was overweight at the time.
3. Protect Your Vehicle and Caravan
Excess weight puts extra stress on your tow vehicle, leading to faster wear and tear on brakes, suspension, and tyres. Knowing your correct weight limits can prevent costly repairs and extend the life of your caravan and vehicle.
Key Caravan Weight Terms You Need to Know
Before hitting the road, it’s important to understand the essential caravan weight terms:
- Tare Weight (TARE): The weight of the caravan as it leaves the manufacturer, with no water, gas, luggage, or personal items.
- Aggregate Trailer Mass (ATM): The maximum allowable weight of the caravan when fully loaded, including water, gas, and belongings.
- Gross Trailer Mass (GTM): The maximum weight the caravan’s wheels can support when hitched to a tow vehicle.
- Tow Ball Weight (TBW): The amount of weight the caravan places on the tow ball of your vehicle.
- Gross Combination Mass (GCM): The maximum combined weight of your tow vehicle and caravan, including passengers, luggage, and fuel.

How to Weigh Your Caravan Correctly
Find a public weighbridge and measure your caravan’s TARE weight (before adding anything inside).
Pack it as you would for a trip, ensuring water tanks, gas bottles, luggage, and food are included.
Revisit the weighbridge to ensure your fully loaded weight is within legal limits.
Step 4: Measure Tow Ball Weight
Use a ball weight scale or a weighbridge to check the weight applied to your tow vehicle’s tow ball.
Weigh your tow vehicle separately and ensure the combined weight (caravan + vehicle) doesn’t exceed the manufacturer’s limit.

Common Caravan Weight Mistakes (and How to Avoid Them)
🚫 Overloading the Front or Rear of the Caravan
👉 Solution: Distribute weight evenly to prevent swaying and instability.
🚫 Relying on the Manufacturer’s TARE Weight
👉 Solution: Always weigh your caravan yourself, as factory weights often exclude extras like aircon, batteries, and accessories.
🚫 Forgetting to Factor in Water & Gas
👉 Solution: A full water tank can add 100kg or more, so always include it in your weight calculations.
🚫 Not Knowing Your Vehicle’s Towing Limits
👉 Solution: Check your vehicle’s maximum towing capacity, ball weight limit, and GCM to avoid straining your vehicle.
🚫 Skipping Regular Weigh-Ins
👉 Solution: Weigh your caravan before big trips and after adding new accessories or modifications.
