Appendix A

Weighing Truck and 5th Wheel Trailer.

Weigh the Truck and 5th Wheel on a public weigh scale. Public weigh scales can be found at Some Truck
Stops, or they can be located from Yellow pages or on the Internet.
Weigh the Truck and 5th Wheel in 3 stages as shown in the sketch.
Step 1, Weigh the both the Truck and 5th Wheel. This is weight 1; this will give the GCW (Gross
Combination Weight) of the Truck and 5th Wheel Trailer. The GCW must not exceed the GCWR (Gross
Combination Weight Rating) for the Truck. The GCWR of a truck depends on engine size, transmission,
rear axle ratio, tow package and other factors. The manufacturer or dealer will be able to find the GCWR
from the VIN (Vehicle Identification Number) of the truck.
Step 2, Drive the front wheels of the truck off the weighing platform. Weigh the rear wheels of the truck
and the 5th Wheel Trailer wheels. This is weight 2, Subtract weight 2 from the weight 1; the result is the
GAW (Gross Axle Weight) for the front axle of the truck. The GAWR (Gross Axle Weight Rating) for the
front axle can be found on the VIN plate on the driver's side door pillar, the measured front GAW must not
exceed the front GAWR on the VIN plate.
Step 3, Drive the rear wheels of the truck off the weighing platform; this should leave only 5th Wheel
Axles remaining on the weighing platform. This is weight 3, Subtract weight 3 from the weight 1 and this
is the GVW (Gross Vehicle Weight) of the truck. The measured GVW must not exceed the GVWR found
on the VIN plate. Subtract weight 3 from weight 2 and this is the measured GAW of the rear axle of the
truck, and must not exceed the GAWR of the rear axle found on the VIN plate. Weight 3 is also the GAW
of the 5th Wheel; this weight should not exceed the GAWR on the plate on the 5th Wheel.
