Mark, Your cargo box looks lovely and will greatly increase your load capacity. But I am concerned about the structural integrity in the torsional failure mode. Are you planning on welding cross members to the base steel beam? I would highly recommend it. That large box with weight in it traveling at highway speeds and going over road bumps is going to generate some substantial forces and probably some sizable torque about the vehicle axis. Just bolting the tray to the beam may not be enough. All the commercial trailer-hitch load trays I've seen have been constructed of welded steel all around - there's probably a reason for all that strength. I hate to think what would happen if your loaded cargo box broke lose on one of those crowded California Highways...
