GarageCalc Read the limits together
Braked towing capacity applies to the loaded trailer, including its ball load. Static ball load is also carried by the tow vehicle and uses its GVM and axle capacity. When adding the measured vehicle and trailer axle loads for GCM, do not count the ball load twice.
Use the matching manufacturer's loading instructions and a weighbridge. The caravan weight calculator checks four entered limits; it does not cover every axle, tyre, coupling, brake or road-rule requirement. See NSW Government towing guidance and the rules for where you travel.
Frequently asked questions
What Isuzu MU-X towing figures are covered?
The named Australian configuration examples below have braked ratings up to 3,500 kg. Coverage is limited to the cited document dates or revisions; no rating is inferred for other years, engines or bodies.
What does "Not verified here" mean?
The cited evidence does not establish that field for this example. It is not zero, and it does not mean the manufacturer has never published a limit. Obtain the manual, vehicle plate and towing-equipment documents matching your exact build.
Does a braked rating establish that my caravan is suitable?
No. Check actual loaded trailer mass, its permitted ATM, ball loading, vehicle GVM, axle limits, GCM, hitch and coupling limits, brakes and manufacturer instructions. The model headline alone cannot certify a combination.
