Abstract
An over the road trailer having adjustable sections to provide different trailer configurations. A flat center bed section has a sliding connection at the front with vertical legs of a gooseneck section and a sliding connection at the back with vertical legs of an L-shaped rear section. Hydraulic jacks move the center section up and down to allow the trailer to assume a double drop deck configuration, a step deck configuration, or a straight deck configuration. Separate power operated and manually operated latching systems secure the trailer in each different configuration.
