I have two drawer magnum size vault with table extension and tie-down rails for sale. Originally designed for 96-02 Ford Expedition, I adapted it for my 2011 Tahoe by removing the folding side wings. Dimensions are 48.5" wide x 14.5" tall x 42.25" deep. Attached is the build sheet from the manufacturer. Have combo and instructions to change. No keys, but available from manufacturer.
Asking $750 picked up in Flower Mound, TX.

Picture of a similar configuration, but the table extension at the bottom is the older design.
