I am Selling my Black UWS low profile tool box. $200 (I paid $311 for it new)
I once had a "bike vise" mounted on the top of it, so you can see that there are two holes drilled in the top that I have sealed with carriage bolts and O-rings. It does not leak. There is also some silicone sealant in that area. Please view the pictures to see what I am talking about. If you want the bike vise back on it I'll give it to you for an additional $20. When it is bolted down and sealed with O-rings it does not leak.
On the inside of the box you can see that the floor is scratched form items sliding around. That will just happen to any box. It also comes with the sliding tray organizer.
I strongly prefer local pick up in Louisiana. I don't even know how I would go about shipping this thing and it would probably be financially prohibitive.
