If you haven't looked into them yet, check out the Milwaukee pack out system. They have tons of different sizes and make organizing everything super easy.
They are also dust/water resistant/damn near bulletproof and super easy to move.
They come in a TON of different sizes. I prefer the slim ones, so i can stack and lock them into places for travel. Its a super slick system really
I have majority of my tools, electrical stuff, air line stuff, and misc spares in packout boxes in my tunnel box. Works perfectly.
Been using them for years and they've become a bit of an obsession thing for me. Hahaha
Heres a pic of how I used them in my Tundra:
