A connector system for coupling a suspension frame device to the rear part of a transport trailer for use in distributing the weight of the load of the trailer to extra wheels and/or providing an effective attachment arrangement for connecting a second trailer behind the first trailer in tandem fashion. The connector system includes a part formed at the front of the suspension frame device which includes a rigid frame portion carried by an additional set or sets of wheels, and the connector system further includes a second part formed integrally at the rear of the frame of the first trailer, the two parts having mating guiding portions for properly aligning the suspension frame device with the trailer as the parts come to an initial hitching position. One of the parts includes a draw bar and the other of the parts includes a connection for attaching to the draw bar in the initial hitching position and pulling the suspension frame device relative to the trailer into a final hitching position whereat the parts are interlocked together. When in the interlocked condition, the engagement between the two parts is such that the frame of the trailer and that of the suspension frame device function as a continuous beam of the first trailer and provide a fifth wheel connection for the second trailer.
