After seeing some great rear cargo storage drawers/platforms/etc. I knew what I wanted. I didn't want to eat up the whole back cargo area's height (I have a dog). So I decided on a drawer that would take the full depth, but only be as wide as the rear passenger seat.
It holds all of my 'truck' stuff. Cables, flares, wind-up radio, air pump, flashlights, water, first aid kit and dog toys.
