tool box/chest

The only thing I worry about with my cheap boxes is the support works for the wheels, and the wheels themselves. I haven't had any collapse on me yet, butIi try not to overload them; which is why I have so many. Well three isn't really many, but you get the idea.
My most-used box has all the popular stuff in it cuz it gets wheeled around, and I keep it light. The other two have the heavy stuff and seldom used stuff;and they stay parked.
I don't think I'm into them for more than $1500Can. The two newest ones are; one from 97, and the other from a little newer;maybe 04ish. Point is I have 10 lineal feet by 42" high plus a small top box, all fit onto my trailer (forklift req'd,yup), for that $1500. That's about 55 cubic ft, or about $27/ ftcu. And since the average age of the boxes is 22, that makes it about $1.23/ft.cu/yr.........S'notsobad,eh?
