Review Axle Weights

A box body has been added to the vehicle and the weight of the body has been added to the calculation beneath the drawing.  Note tare (or curb) weight of the vehicle, gross vehicle weight rating (GVWR), body weight, weight distribution over each axle, as well as total truck weight and maximum payload achievable with this configuration.  The Permissible weights are the ‘lower of’ maximum weights allowed by the vehicle manufacturer and the legislation that has been applied to the calculation.
