was in Harbor Freight one day and saw the complete U.S. General roll around toolbox set up. The next day I came back and bought the whole thing. Best toolbox and accessories going! Plus you can't beat the price. I set it up at my job in a mechanical/machine shop and the gravitational pull of this thing was awesome. Everyone wanted one. That was in summer 2009. since then I've had to move it (relocate it) TEN times, to ten different job sites. Moving the U.S. General is tough on it and it's a lot of work. My advise is to not take short cuts when and if you have to relocate it and here's why. The roller bearings in the drawers are tough and all, but it is easy to damage them if you take the draws out and then try and put them back in without emptying them first. Also, the drawers for each attachment of the whole collection of tool boxes are NOT interchangeable with each other. If you take a drawer out, make sure it goes back into the same tool box... If you get the drawers mixed up and just put drawers in wherever, you WILL damage them. I couldn't figure out why some of the drawers were not sliding correctly, so I applied extra pressure to get them to go. Big mistake! Those bearings work great if you're careful and match the right drawers with the right boxes. But if you don't the bearings get damaged easy and then the drawers don't slide very well and in some cases it will cause the box not to lock properly because the locking mechcanisim on the back of the drawers may be bent out of shape. That's what happened to me. I got in a hurry and damaged several of the drawers by forcing them into the wrong slots. I was able to do some repairs to it after I realized what was wrong; however, I now have 10 roller bearing drawer slides that need replaced. They're riveted on the inside of the boxes and they support the drawers. But I haven't been able to locate any replace parts for the U.S. General boxes
