Driving
If you are adding weight to the front
of your vehicle (potentially
including weight added to the cab),
the weight added should not
exceed the Front Axle Reserve
Capacity (FARC). Additional frontal
weight may be added to the front
axle reserve capacity provided you
limit your payload in other ways (i.
e. restrict the number of passengers
or amount of cargo carried).
You may add equipment throughout
your vehicle if the total weight
added is equal to or less than the
Total Axle Reserve Capacity
(TARC) weight. You should NEVER
exceed the Total Axle Reserve
Capacity.
Always ensure that the weight of
passengers, cargo and equipment
being carried is within the weight
limitations that have been
established for your vehicle
including both Gross Vehicle
Weight and Front and Rear Gross
Axle Weight Rating limits. Under no
circumstance should these
limitations be exceeded. Exceeding
any vehicle weight rating limitation
could result in serious damage to
the vehicle and/or personal injury.
