A lot of guys out where I work have the harbor freight U.S. General tool box. Its top doubles as a nice workbench. Wide top drawer, and double drawers. We call em "Taco Wagons"
Harbor freight one comes in different colors of powdercoating, pretty heavy cage steel, and roller bearing drawer slides. Not super super expensive either. If they had these when I bought my Mac Tech 1000 series I woulda bought one of these instead.
BTW the dog dishes fit 13", 14", 15" steel wheels.
