Terry, obviously we all agree with the basic claim that one has to consider axle capacity, Spring capacity, Tire capacity and Braking. DUH!!

While coming up with your own formula, you introduced a flawed belief that the load capacity of a half ton truck is actually a half ton. That is incorrect.

Axle weight capacity should mean just that. Combined axle weight seems to mean total capacity... truck, cargo, gas & oils. Perhaps the term axle capacity is too nebulous.

Provided one has the proper springs, tires and braking it is fair to say the the total weight should not exceed the axle capacity.
