I stumbled across a manufacturer’s video of the Decked System last year, thought it was interesting, and then forgot about it until I saw it again a few weeks back at the Work Truck Show. It consists of a deck that can support 2,000 pounds with a pair of 4-foot drawers below. Sizes are available to fit a variety of trucks with 5’6” and 6’6” beds. The system is waterproof and can be installed in the open bed of a truck.
See the video below for details.
