Storage using bed rails?

Does anyone have any type of storage system that mounts to the bed rails?

For context, I have a cargo glide drawer. I set some things along side of the tray that get bumped and moved under. I am envisioning some kind of basket or shelf I can mount to the bed rail to keep these items up and out of the way of the tray while remaining accessible.

Any ideas?

 

This may inspire you. It is on a newer Tundra but a similar mod could be done on Gen 2/2.5:
