Abstract: A trailer includes a bed with a floor structure and a superstructure mounted on the bed. The superstructure includes a wall construction of wall sections with interconnected tongue-and-groove edges and wall section ends. Corner posts include channels receiving the wall section ends for forming corners of the superstructure. A top rail forms a rim of the superstructure and receives the top-most wall sections. A rub rail connects the walls to the floor structure and receives the bottom-most wall sections. A method of manufacturing a trailer includes the steps of providing a bed with a floor structure and forming a superstructure from wall sections by interconnecting their tongue-and-groove edges. The trailer can be configured for a moving floor, a tipping mechanism or an ejector mechanism for discharging and/or loading materials and cargo in an interior.
