Crew Cab Truck Bed Storage

[69supersport]

Does anyone know where I could find a truck box that would be big enough to fix straps, tow ropes, and more but small enough to fit on the inside corners of my bed. I need something tall, and thin so my bed space is not affected. This is the hard part, with a 5'8" bed I have only found truck tool boxes but many are too large, and the over the wheel well ones are nice but what im really looking for is something like what you see on the new gmt-900's that are using the bedrail management system.

Thanks

Not sure about boxes for the bed, but I'm considering a storage box for behind the rear seats in my crew cab. It's made by Du-Ha:

Maybe it's big enough for then items you want to store.
