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.
