A trailer having a plurality of sliding side doors as well as conventional rear doors permits side access to the trailer interior, enhancing cargo loading and unloading speed and flexibility. At least one side of the trailer includes full length upper and lower tracks, each upper and lower track slidably receiving a set of trolleys which support and guide an individual door. The trolleys are coupled to the doors by pivoting arms which move between two positions. In the first, closed position, the door is in substantial vertical alignment with the tracks and may be latched to the trailer proper such that it functions as a portion of the sidewall; in the second, open position, the door is spaced laterally from the tracks and the other doors such that it may be slid along the full length of the trailer. The trailer also includes special hardware for facilitating securing the doors to the trailer body, slidably opening them, flexibly sealing adjacent doors and removing door weight from the trolleys and tracks when they are closed.
