GMC SIERRA DENALI 2002 Manual page 228

2-Tiered Loading
By positioning four 2 x 6 wooden planks across the
width of the pickup box, you can create an upper load
platform. The planks must be inserted in the pickup box
depressions. The length of the planks must allow for at
least a 3/4 inch (2 cm) bearing surface on each end of
the plank.
When using this upper load platform, be sure the load is
securely tied down to prevent it from shifting. The
load's center of gravity should be positioned in a zone
over the rear axle. The zone is located in the area
between the front of each wheel well and the rear of
each wheel well. The center of gravity height must not
extend above the top of the pickup box flareboard.
Any load that extends beyond the vehicle's taillamp area
must be properly marked according to local laws and
regulations.
Remember not to exceed the Gross Axle Weight Rating
(GAWR) of the front or rear axle. See "Loading Your
Vehicle" in the Index.
Add-On Equipment
When you carry removable items, you may need to put a
limit on how many people you carry inside your vehicle.
Be sure to weigh your vehicle before you buy and install
the new equipment.
