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. Caravan Weight Distribution of 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.
Weight Distribution
When a caravan or trailer is connected to a vehicle, there is an inevitable addition of weight to the rear of the vehicle. The added weight can alter the handling of the vehicle due to the imbalance of weight from the front to the rear.
Diagram 1 : Incorrect Weight Distribution
Weight Distribution Hitches correct this by redistributing the weight across all axles of the vehicle and caravan (as shown in Diagram 2), much like the lifting action of a wheelbarrow.

Weight Distribution Hitches have been designed & engineered to ensure towing vehicles operate at their optimum braking, steering and general driving capacity.
What Are the Key Caravan Weight Distribution terms 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.
