Fully assembled storage bin for extended cab pickup truck

A pre-assembled rectangular bin that fits on top of the back section of the back seat of an extended cab pickup truck. The bin consists of a rectangular body formed with a front panel, two end panels, a bottom panel and a back panel. The back panel is longer than the front panel, creating an extended portion. The extended portion of the bin fits behind the back seat of an extended cab pickup and supports the actual bin which is thereby positioned on top of the back seat in a manner that allows full access to the storage area of the bin. Installation involves slipping the extended portion of the bin over the back seat. To remove the bin, pick it up and take it out of the truck. Two divider panels are provided and can be slipped into place in the tracks inside the bin thereby providing the option of one, two or three separated storage spaces within the bins interior.
