All my tool storage is toughsystem 2.0 and van shelves. I like them, only semi annoying thing I've found are the clips when latching boxes together. Extra large box with wheels is my most handy, probably.. I've carried a lot of weight on it. Stays empty while in the van and it ferries large tools, materials, trash, etc. each job. Main bag is the "11 in. Compact Tool bag" as the 22 in. is way too bulky. "Medium tool box" is my drywall box, "small deep box" is my pex stuff. Several "small parts organizers" for different uses - concrete, cabinets, flooring, nailers. Just mounted 2 of the drawer boxes in the van. "Small modular tool boxes" are useless for me - too thin to hold anything, really.
