Abstract: A work surface that attaches to a portable transportation and storage device is provided. The work surface has a tray and legs. The tray has a planar top surface defined by a rear edge, a front edge, and side edges. A lip extends upward from the top surface along each edge. Attachment points on the tray mount the tray to the portable transportation and storage device. The legs have a leg clamping device that mounts the legs to the portable transportation and storage device. The legs include a height adjustable portion configured to selectively extend the length of the legs, and a pivot portion that is rotatable relative to the height adjustable portion.
