Chevrolet 2004 Silverado 1500 Pickup Owner's Manual page 352

If you put things inside your vehicle – like suitcases,
tools, packages, or anything else – they go as fast as
the vehicle goes. If you have to stop or turn quickly,
or if there is a crash, they'll keep going.
{
CAUTION:
Things you put inside your vehicle can strike
and injure people in a sudden stop or turn, or
in a crash.
•
Put things in the cargo area of your
vehicle. Try to spread the weight evenly.
•
Never stack heavier things, like suitcases,
inside the vehicle so that some of them
are above the tops of the seats.
•
Do not leave an unsecured child restraint
in your vehicle.
•
When you carry something inside the
vehicle, secure it whenever you can.
•
Do not leave a seat folded down unless
you need to.

Payload
Payload capacity is the maximum load capacity that your
vehicle can carry. Be sure to include the weight of the
occupants as part of your load. If you added any
accessories or equipment after your vehicle left the
factory, remember to subtract the weight of these things
from the payload. Your dealer can help you with this.
Remember not to exceed the Gross Axle Weight
Rating (GAWR) of the front or rear axle.
