I've been looking for a mobile solution to haul around a set of hand tools. I'm looking at this rolling packout box for sockets, wrenches, hammer, etc., with a few organizers on the lid for smaller stuff like pliers and screwdrivers. The packout is rated for 250 lbs, but I'm worried that over time the amount of tools I would be hauling (about 50-60 lbs), might take its toll on the box. Is the packout system tough enough to handle that weight?
