This doubled walled aluminum slip tank has two sides: One side is 300L and the other is 70L I had intended to use it for both diesel and regular gasoline on the farm, but I didn't end up needing it very much. The slip tank has been emptied out with a vaccuum. The mounting brackets were broken when I got it (Aluminum is apparently difficult to weld), they could be replaced with caution now that both sides are empty. I kept cardboard on top and in front of the tank to protect it from scratches. It is 19 inches tall x 24 inches x with a few inches of space on each side of the truck box.
