Towing a caravan is one of the best ways to explore Australia’s vast landscapes, but nothing ruins a trip faster than exceeding your towing setup limits. Overloading your vehicle or caravan can lead to fines, mechanical failure, or even serious accidents. According to the National Heavy Vehicle Regulator (NHVR), incorrect weight distribution is a leading cause of towing-related incidents on Australian roads. This guide from Caravan Weight Check will walk you through everything you need to know to stay under your legal and safe towing limits — including GVM, GCM, ATM, TBM, and tow ball mass. Follow these steps to ensure your next adventure is safe, legal, and stress-free.
What Are the Key Towing Setup Limits in Australia?
| Term | Meaning | Typical Limit |
|---|---|---|
| GVM (Gross Vehicle Mass) | Maximum weight of your tow vehicle (including passengers, fuel, accessories) | Stated on vehicle compliance plate |
| GCM (Gross Combination Mass) | Total allowable weight of vehicle + caravan/trailer | Found in owner’s manual or compliance plate |
| ATM (Aggregate Trailer Mass) | Maximum weight of fully loaded caravan | On caravan compliance plate |
| TBM (Tow Ball Mass) | Downward weight on the tow ball (usually 10% of ATM) | 150–350 kg depending on setup |
| Kerb Weight | Unladen weight of vehicle (no passengers/fuel) | Varies by make/model |
Pro Tip: Always check your vehicle’s compliance plate (usually inside the driver’s door) and caravan VIN plate for exact limits.
