Review on DEWALT DWST17807 TSTAK Toolbox Organizer by Daniel Elgee

I bought this model as the top of my truck, I will attach some photos of its size and inner workings. Got this for my OSC tool and corded drill, love the top compartments for storing all the drills and screw bits. It feels pretty tight and secure, I'm not sure I would trust it to fall off the bed of my truck. But simply tipping over or accidentally dropping the item might be ok. I'm curious when this will be used.
