An integrated work surface assembly for a motor vehicle cargo area includes a substantially planar workpiece configured for translation along a pair of cargo area closure panel support arms between a fully stowed configuration and a fully deployed configuration. A recess in the cargo area closure panel receives and holds the workpiece in the fully stowed configuration. Each support arm includes a guide slot for slidingly translating the substantially planar workpiece between the fully stowed configuration and the fully deployed configuration. Stops are provided for arresting downward translation of the workpiece in the fully deployed configuration.
