Caravanning is a cherished part of the Australian lifestyle. It offers freedom, flexibility, and a deeper connection with the land. But too many caravan owners hit the road without knowing if they’re safely and legally within weight limits—and the risks of getting it wrong can be devastating.
Vanweigh specialises in helping caravan owners understand their true towing weight through precise, mobile weighing services. The importance of weighing your tow vehicle and caravan goes far beyond compliance—it’s about protecting lives, property, and financial security.
Why You Must Know Your Weight
It’s easy to assume that if your car can tow a certain number on paper, then you’re in the clear. But the real picture is far more complex. Between payload limits, axle loads, tow ball weight, and gross combined mass, there are nine separate weight-related limits that can be exceeded—and many of them have serious consequences if breached. Even seemingly small additions like extra water, solar batteries, food, or a generator can push you over the edge.
The Real Cost of Overloading
Overloading affects handling, braking, stability, tyre performance and suspension integrity. It dramatically increases wear and tear on your vehicle and caravan—leading to costly repairs and early component failures. But far worse is the legal and insurance impact.
Your Insurance May Not Pay Out
In the event of an accident, if your caravan or tow vehicle is found to be over the legal limit, your insurance company may refuse to honour your claim. This could leave you footing the bill for your own losses—and potentially others’—even if the accident wasn’t your fault.
You Could Be Held Criminally Liable
We’ve seen this go horribly wrong in real life. One tragic case involved a driver towing an overloaded caravan. An accident occurred, resulting in the death of two passengers. As the investigation revealed, the combination was significantly overweight, meaning the insurance company denied the claim. The driver was ultimately charged and served six years in prison for dangerous driving causing death. This is not fear-mongering—it’s reality.
Even Passive Drivers Are Scrutinised
Not all incidents involve reckless driving. One of our customers, a retired couple, were parked on the side of the road making tea. Another driver suffered a fatal medical episode and veered into their parked car and caravan. Though the couple were entirely passive in the incident, police and the coroner still ordered their combination to be weighed. Fortunately, they had recently been checked by Vanweigh and were just under all legal limits—avoiding further distress and possible legal complications.
Why Mobile Weighing Is Far Better Than a Weighbridge
Many caravan owners assume a cheap visit to a public weighbridge will give them the answers they need—but it’s not that simple. Public weighbridges are primarily designed for heavy trucks and industrial freight.
They are:
• Calibrated at much higher weight ranges—typically for 20,000 kg+ vehicles.
• Inaccurate at caravan weights—weighbridges usually work in 50 kg increments, which is not precise enough when many weight limits (like tow ball weight) must be met within very small margins.
• Unstaffed or transactional—you drive on, get a number, and drive off. There’s no breakdown, no explanation, and no personalised assessment.
In contrast, Vanweigh’s mobile weighing service is specifically calibrated for caravans and tow vehicles. Our mobile weighing pads:
• Measure in 1 kg increments, providing highly accurate readings for your setup.
• Are calibrated at the weight range that caravans and tow vehicles operate in, ensuring meaningful accuracy.
• Measure each individual wheel, allowing us to calculate axle loads precisely and identify imbalances or dangerous distributions.
• Let us check all 9 critical weight areas: GVM, GCM, ATM, GTM, tow ball weight, front/rear axle loads (car and van), and more.
And perhaps most importantly—we take the time to explain what each number means.
Personalised Education, Not Just Numbers
Vanweigh’s service doesn’t stop with a printout. We sit down with you and explain how your results affect your legal compliance, road safety, and the longevity of your vehicle and van. We’ll point out potential red flags and offer practical advice on how to redistribute or reduce weight if needed. That level of personal care and education simply isn’t available at a weighbridge.
Peace of Mind You Can’t Put a Price On
Caravanning is about enjoyment and freedom—but that should never come at the expense of safety. Getting your caravan and tow vehicle weighed professionally means you can travel confidently, knowing you’re doing the right thing not just for your passengers and your gear—but for every other driver on the road.
Before your next trip, ask yourself:
• Am I 100% sure I’m under every legal limit?
• Could I explain my setup confidently in the event of an accident?
• Would my insurance pay out if the worst happened?
If the answer to any of these is “I don’t know,” then it’s time to get weighed—properly.
