Rear Gross Axle Weight Rating (RGAWR) from
the certication label located inside the driver-side
door jamb or door.
4. With the occupants in the truck for normal hopper
spreader operation, weigh the vehicle to obtain
gross vehicle weight (GVW).
5. Subtract the GVW from the GVWR to determine
the available material payload.
6. Obtain the weight per cubic yard (lb/yd3) of the
desired material. Divide the weight into the
payload to determine the maximum volume of
material that can be carried.
7. Refer to the Load Volume table and diagrams to
determine the maximum ll level for the material.
8. Fill the hopper with material to the calculated level.
Reweigh the vehicle with occupants and verify that
the Loaded Gross Vehicle Weight, Front Gross
Axle Weight, and Rear Gross Axle Weight are less
than the vehicle's ratings.
9. Repeat Steps 6–8 for each type of material.
The worksheet for Determining Vehicle Payload (next
page) includes an example.
