alminum, no steel!, so go anodized if ya gotta have black. paint sucks
I had one of the aluminum boxes on my motorhome, was Great, real thick, and held up well to the sand and salt.
For tools or tackle?
I gotta find a pic... I had a white fiberglass one on my 79 chevy... over the winter I fabricated a divider,, drivers side was a tackle box, passengers side was a cooler...
