I would find it hard to say it is the ultimate toolbox without trying it.
-Assuming there are no roller slides?
-do the drawers have stops, or do they fall out, or is this part of the design to carry a drawer to the job?
-A 100+ lb. Tool box is heavy for me. I see wheels but the beauty is the portability of lifting it into a truck, jeep, atv, ect. That would not work for a guy like me who has a 50lb work restriction.
For me a few $20 home improvement plastic tool boxes is a better setup for mobile tools.
That is what I use in my trucks aluminum toolbox.
Might work better for someone who always works as a team, maybe the military(I was not in the military so don't know how they work). I say might work for a team because you would have help lifting it.
