That's a damn nice tool setup!
My F350 is a rolling toolbox...
I have the 4 small tool boxes under the flatbed, the big toolbox/transfer tank on the back, and 3/4 of the back floorboard is tool box and tool bags.
If I'm out on a project and have to work on a tractor or shredder, I want my tools with me. (I carry the air tools as well. Impact, etc.) Like you, I carry lots of sockets and ratchets too.
Wish I could get a toolbox like that, but pulling my gooseneck prohibits that.
