Method notes 3 notes

Axle load = empty axle weight + each added load multiplied by its entered front/rear split.
Additional cargo capacity uses the same cargo rear-axle split and is limited by GVWR, front GAWR and rear GAWR.
Use certified scale weights, tire/load ratings, hitch ratings, local regulations and manufacturer placards for real fleet or towing decisions.
