VEVOR Semi-Truck Step Tool Box, 760 x 750 x 400 mm Heavy Duty Aluminum Diamond Plate Toolbox, Waterproof Cab Entry Step Storage Box with T-Handle Lock & Keys for Flatbed, Crane, and Semi Trucks

Aluminum made storage box is tough and wear-resistant. It comes with safe lock design to store tools and small parts neatly. Perfectly installed on trucks and engineering vehicles for outdoor work storage.

For the most part, this box is pretty well built. Aluminum is thick enough to hold quite a bit of weight and the construction is excellent. However... The very top step is a horrible design as if no one was using common sense when they put it on. The traction holes on top are open and water/dirt/debris can enter, but the bottom of that step is completely closed off meaning anything that enters those holes will remain there until it fills up. I'll be keeping the box and just drilling holes to hopefully allow whatever goes in to get out. But, just keep in mind that it has one of the worst design flaws you can have for something like this. It's a great box for the money, but someones lack of common sense completely messed that up.
