Doesn't have to necessarily be an ammo can, but some sort of metal, water-proof, military type container.

What I am looking for is something about 30 - 40 inches long, about 12 inches wide, and probably 8 - 12 inches tall.

Trying to install a permanent "dry box" on the back of my ATV that will hold all of my crap.

I know the "box full of stuff" that was going around was a bit larger than your usual ammo can and was hoping I could find something similar.

Thanks in advance.
