That looks sharp. It is always nice to have more secure storage that is out of the weather and out of reach of the opportunist type of thief?
Add a Carpet / Bed kit and you have a nice little camp out spot for those times you just get stuck out on the road, want a quick and simple place to nap, or head out somewhere that you just wouldn't want to tow a Travel Trailer, etc.
I keep thinking about one, but then am confronted with an occasion when I need to carry something tall in the bed; Motorcycle, Quad, Dog House, etc.
Plus, I am always picking up discarded trash and items that have blown out on the road, like cardboard boxes, chunks of firewood, coolers, old rope / line with boat anchors or whatever. Though locking things up is nice, sometimes it sure is convenient to just jump out, pick up whatever the item is, toss it in back and head on down the road real quick and easy without unlocking things, opening lift gates and all that.
Sure you can take them off, but who has four tall, strong friends handy when that time comes? And where do you store it so that it doesn't get scratched up or knocked over when off the truck?
