A water truck body comprising a floor, two side walls, a front wall and a rear wall, a plurality of cylindrical baffle bodies with open bottom ends, a top plate situated on top of each of the cylindrical baffle bodies so that the cylindrical baffle body is centered underneath the top plate, and a tubular support structure. Each of the plurality of cylindrical baffle bodies comprises a plurality of apertures configured to permit liquid to flow through them. The tubular support structure is configured to hold the top plates and provide structural stability to the side walls, front wall and rear wall.

A quasi-cylindrical cargo container is formed of a plurality of rigid, curved panels together forming first and second semi-cylindrical shells, and a plurality of rigid, flat extension panels bridging the first and second semi-cylindrical shells. A method of manufacturing the container includes forming the first and second semi-cylindrical shell from the curved panels, forming the quasi-cylindrical shell from the first and second semi-cylindrical shells and the flat extension panels, forming collars conformably encompassing the quasi-cylindrical shell, constricting the collars to compress joints formed at abutting edges of pairs of adjacent panels, rolling the shell and collars sequentially to bring the joints to a lower position, welding inside seams of the joints when at the lower position, removing the collars, rolling the shell sequentially to bring the joints to an upper position, and welding outside seams of the joints when at the upper position.

A trailer that has a main body having a front bulkhead, an opposing rear bulkhead, an exterior wall operably engaged with the front and rear bulkheads, and at least one interior chamber defined collectively by the front bulkhead, the rear bulkhead, and the exterior wall. The at least one interior chamber is adapted to carry a load. The trailer also includes a removable false bulkhead operably engaged with the main body. The false bulkhead is located a distance away from one of the front bulkhead and the rear bulkhead.
