FORD 2006 F-550 v.1 - Manual (Page 147)

Payload – is the combined weight of cargo and passengers that the
vehicle is carrying. The maximum payload for your vehicle can be found
on the Tire Label (vehicles exported outside the U.S. and Canada may
not have a Tire Label) on the B-Pillar or the edge of the driver’s door.
Look for “THE COMBINED WEIGHT OF OCCUPANTS AND
CARGO SHOULD NEVER EXCEED XXX kg OR XXX lb.” for
maximum payload. The payload listed on the Tire Label or Safety
Compliance Certification Label is the maximum payload for the vehicle
as built by the assembly plant. If any aftermarket or authorized dealer
installed equipment has been installed on the vehicle, the weight of the
equipment must be subtracted from the payload listed on the Tire Label
or Safety Compliance Certification Label in order to determine the new
payload.
The appropriate loading capacity of your vehicle can be limited
either by volume capacity (how much space is available) or by
payload capacity (how much weight the vehicle should carry). Once
you have reached the maximum payload of your vehicle, do not add
more cargo, even if there is space available. Overloading or improperly
loading your vehicle can contribute to loss of vehicle control and
vehicle rollover.
