The pickup box was designed for the use of add-on equipment. However there are specific mounting points that must be used along with weight
restrictions, refer to the following: Chart 1 - Weight Restrictions for Pickup Box Add-Ons. Structural members have been added to provide load paths
directly to the platform cross-sills and into the vehicle frame. Aftermarket accessories should take advantage of these intended load paths as detailed
below in Figures 1-4. Depending on the accessory design, it may be necessary to add some form of a spacer under the accessories at the structural hard
points to take up any gap. Do not use the GM Cargo Management Option mounting points for attaching anything other than the GM Cargo Management
system as referenced in Figure 5.
