  • Patent number: 6478355
    Abstract: A pick up truck configuration is adaptable for carrying a cargo load longer than the cargo box and preferably at or above the wheel covers protruding into the cargo box. An adaptable pick up truck configuration includes a cab portion and a cargo box. A box panel portion is pivotally connected to a front wall of the cargo box and is movable to a generally horizontal position in which the box panel portion partially overlies and is supported by the wheel covers. The cargo box includes a cargo box opening when the box panel portion is in the generally horizontal position. A cab panel portion is pivotally mounted to the cab portion and is movable between a generally vertical closed condition and a generally horizontal open position. The cab portion has a cab opening when the cab panel portion is in the generally horizontal position and the cab opening is at least partially aligned with the cargo box opening.
