What do you think of this tool storage system?

exactly as a Union Carpenter working in the Reno Division of a major Construction company in my home market I have complete sets for different types of work , I do a lot of fine finishing and reno work but also have to do heavy Carpentry and concrete so I can just load the boxes that apply to the job I am doing and don't have to re organize every time I change sites which can be daily . Some small renos there's no budget for plumbing and electrical rework so I have to be ready for anything .
