Abstract: An extendable tool box includes a tool box, a table top and support legs. The tool box may be slidably reciprocated along a first horizontal travel path aligned parallel with the truck bed. The table top may be contiguously oriented parallel with the tool box and slidably reciprocated along a second horizontal travel path registered parallel to the first horizontal travel path. The tool box may include a bottom surface having a cavity whereby the table top may be stowed. A sliding mechanism may be connected to the bottom surface of the tool box and may permit the tool box to freely reciprocate along the first horizontal travel path. The support legs may be telescopically adjustable between extended and retracted positions. The tool box may include a plurality of storage compartments arranged on left and right longitudinal sides and equidistantly offset along a central longitudinal length of the tool box.
