Those trays specifically for that box or just stuff you found that happened to fit? I like it. Nut drivers are an interesting site in a motorcycle tool box, I don't think I've ever used one on a bike before.
The trays I picked up are universal, but fit really well. As for the nut drivers, I basically never use them. They work well for band clamps vs. using a flat blade screwdriver. I think it's these: https://www.harborfreight.com/6-compartment-drawer-organizer-99729.html
Thought your rig looked familiar, you were at the Ken Hill school last week at VIR. I was the bald guy on the 890 Duke. Looked like a great set-up you have—I especially liked the Marine sticker! I rented a Promaster for the school and really liked the van thing. I’m thinking of going down the race van rabbit hole, lol.
