A storage enclosure for a vehicle includes a seatback, an outboard member, a ceiling, and a tray. The tray includes a base with at least one wall extending upward from the base. The tray is selectively operable to transfer cargo between a passenger area and a cargo area. The tray is selectively operable to define the storage enclosure in the cargo area that is at least partially defined by the seatback, the outboard member, and the ceiling. The seatback is in a substantially vertical position.
