They are steel tanks. The picture show both tanks bottom being held in place with two straps across the bottom (see attached picture). The straps has rods that run up to the wood floor in the bed. You can see the tank are hand made, referencing the welds. This weekend I'll get them out of storage and take some pictures and post it here.
If you still want them after I post the pictures, you only need to pay the freight.
The attached picture is about 4 years old (when I first look at the truck) and the truck bottom now look a 1000% better.
The tanks that I want to have will be attached to the frame, but I do not know when I will get that far along.
