Back on topic, I plan to do a drawer system. One of the more well known brands is Truck Vault. I've had some work trucks that had them installed, and they seemed to be very well built. I'd like to have one that basically fills in the rear storage area and is the same height as the folded rear seats, to make the entire area behind the driver's seat as close to the same height as possible, to be able to sleep in the area if needed. They are not, however, removable, rather are security biased and usually bolted in.
