I gotta ask: how are the slides on those US General? I have quite a few large boxes, but most are older Craftsman from Craigslist. Some have OK slides although not that sturdy, others are terriby flimsy and bind if I overload the drawer. But all in all it seems to me that the slides are probably the most important thing in a drawer tool box. So, do they roll easy when loaded, do they tend to bind or bend sideways?
And on the more practical side, I see some of those weigh 2 or 300 lbs. I imagine they come unassembled. Do they come in separate smaller boxes so they are easy enough to load and unload alone in a truck or is it a big ordeal?
