A large haul box for use in a pickup or trailer is disclosed. The large haul box includes a pair of long side wall having a top side, a bottom side, an open end and a back end, a back wall coupled between the back ends of the pair of long side walls, a bottom surface coupled to the back wall along a short end and coupled to the pair of long side walls on their bottom sides, a bottom sheathing coupled to the bottom surface, a long side sheathing coupled to each of the pair of long side walls, a back sheathing coupled to the back wall, and a removable box end having a top side, a bottom side, and a pair of short sides between the top and bottom sides for coupling to the open ends of the pair of long side walls along the pair of short sides and oriented to have the bottom side of the removable box end couple to the open end of the bottom surface.

The invention relates to an inexpensive technique and procedure to add storage capacity to existing hydrocarbon storage tanks that have a double seal floating roof. The additional storage capacity is obtained by installing an extension that is strong enough to provide the upper seal of the double seal arrangement to maintain a sealed vapor space that allows the roof to move higher within the existing peripheral wall of the storage tank.

A large capacity above ground impoundment tank includes a number of first-level interlocking panels connected to one another to form a generally circular tank. The first-level interlocking panels include a plate, a first flange, a second flange, a third flange, and a fourth flange. The first-level interlocking panels include at least retaining rib and at least one vertical support member. The third flange of each first-level interlocking panel includes a guide pin. The first flange of a first-level interlocking panel is connected via suitable fasteners to the second flange of an adjacent first-level interlocking panel. A number of second-level interlocking panels may be positioned on a top surface of the first-level interlocking panels. The second-level interlocking panels may be similar to the first-level interlocking panels. The guide pin of a first-level interlocking panel is inserted into a corresponding guide pin hole on the fourth flange of a corresponding second-level panel.
