Nice! I don't have a toolbox, so what I did was bolt a beefy piece of angle aluminum the full with of the front bed rail, then thread a bunch of eye-bolts into it at scuba tank spacing. Then got bungees to loop around the tanks. And I painted it with black spray on Bedliner. Holds 8 tanks securely for when 4 of us would go do 2 shore dives in an afternoon. Unfortunately it got replaced by a tonneau cover, and we don't have any scuba friends in the keys to need 8 tanks. Everybody just freedives, uses a hookah to lobster, or just fishes from boats.
