I tell you what I really want is an OEM side access toolbox. Basically, use the wasted space below the bed, in front of the wheel on each side, to make a small dry box.
Much like the underbody boxes you see on flatbeds, but factory built into the sheetmetal, to retain the pickup lines. Dodge came close when they built the top access into the bed sides, but I'd much prefer have the lower side access, and not lose bed width.
Just need enough space to store straps, extra trailer hitch, recovery chain, etc, without having them bouncing around in the bed, or loose in the cab. For someone who often hauls with a truck, a toolbox across the bed eats up too much space - can't slide two pallets into the bed with a toolbox there. The side boxes that are designed to fit between the wheel well and the front of the bed are clever, but when carrying 5x10' sheets, that space is needed. Tonneu covers make the bed useless for any real loads.
Any auto designers listening?
