Vehicle — Measured Inputs

Rego Number (Vehicle)

Front Axle Load — measured

Measured on scales while hitched.

Rear Axle Load — measured

Measured on scales while hitched.

Vehicle Loaded (hitched) = Front measured + Rear measured.

Trailer — Measured Inputs

Rego Number (Trailer)

ATM Actual — Unhitched

Trailer on jockey wheel, unhitched.

GTM Actual — Hitched

Trailer weight on wheels when hitched.

TBM — Measured

Vertical load at tow ball (download).

If you only know two of ATM / GTM / TBM, enter those and set the third to 0 — the calculator will derive the missing one using ATM = GTM + TBM.
