Use the sourced figures shown below, then enter any missing ratings from documentation for your exact vehicle when completing your assessment. Customer-entered figures are not independently verified. Leave unknowns blank: affected checks cannot be assessed, and this page is not a complete setup clearance.
A weighbridge establishes actual loads, not permitted limits. Do not substitute figures from another year or variant.

How TowSense verifies this page
TowSense checks published specifications against Australian source documents. Source checked records pass automated extraction, identity and calculation checks; human review is reserved for exceptions. Manufacturer documentation is preferred, but where manufacturers do not publish a particular specification, TowSense may use recognised technical or independent Australian sources and identifies that source clearly. Calculated values are labelled separately. We do not estimate missing manufacturer limits.
Can this vehicle really tow its headline capacity?
The braked towing capacity is only one constraint. The complete setup must also remain within the applicable GVM, GCM, towball, front axle, rear axle, towbar, coupling and tyre limits. Passengers, luggage, accessories and towball load consume vehicle capacity.
Payload and accessory impact
Bullbars, winches, canopies, drawers, auxiliary batteries, long-range fuel, recovery equipment, roof loads, passengers and towball download all contribute to the loaded vehicle. Check actual fitted weights and positions rather than relying on advertised payload alone.
