Always check your compliance plate
Online databases use factory-standard specs. They do not know about the bullbar on your car, a suspension upgrade, or how much you are carrying. Each one changes your real limits.
How to find it
Open your passenger or driver door. Look for a silver or black metal plate riveted to the pillar. This plate overrides everything you read online.
Why the numbers move once you load up
The figure most often left out of the sum is payload, which is everything you add after the vehicles leave the factory.
- • Bullbar and winch: both add weight to the front of the car, and it comes out of your payload.
- • Passengers: everyone in the car, including the driver, comes out of its payload.
- • Ball weight: the weight the van puts on the towball comes out of your car's payload as well as its towing limit.
Work out what this van is allowed to carry, then check the figures before you pack it.
Always weigh your rig fully loaded.

At this weight, Australian law requires towing mirrors and a brake controller. Check you have both before the first trip.

Legally required when the van is wider than your car
See towing mirrors on Amazon.com.au →Brake controllers

Figures come from the makers' published specs for this exact pairing.
This is a guide off the makers' published figures.The legal numbers are the compliance plates on your car and the van. Where we do not hold a published ball weight, we estimate it at 10% of ATM.Weigh the loaded rig at a public weighbridge to know for sure, then read the ticket.
Where the published weights sit close together, how you pack changes what the scales say. Heavy items ride best low down and over the caravan's axles, and whatever sits on the towball is carried by the car rather than by the van.
