This collective page covers the trailers and semi-trailers that the register does not assign to a named series. Fruehauf of Detroit is regarded as one of the pioneers of the semi-trailer: company founder August Fruehauf built one of the first semi-trailers, for a motorboat trailer, in 1918, laying the groundwork for the later separation of tractor unit and trailer in freight transport.

The register lists 4 versions with a kerb weight of 3,600 to 10,190 kg and a permissible gross weight of 18,000 to 39,000 kg. Lengths reach up to 13.90 m, widths from 2.50 to 2.55 m.

With gross weights of up to 39 tonnes, the semi-trailers fall into the typical long-haul range, hauling goods over long distances as part of articulated combinations. Type codes such as FKSRT4 indicate the body variant and axle count within the manufacturer's range. Kerb weight across the four versions varies by more than 2.8 times, pointing to different axle counts and body variants within the range.

When buying used in this weight class, the condition of the frame, side members and welds matters most, as they are heavily stressed in long-haul operation. The brake system, axles and kingpin plate should be checked carefully, along with the condition and tightness of the bodywork. Spare parts for axles, brakes and the coupling are available through the general commercial-vehicle accessories trade.
