Since there is no need to connect to the front of the tractor, the connection mechanism of the full draw bar trailer is relatively simple. The body and the towing section are usually connected by a hinged connection.

The cargo carrying structure is relatively independent, usually using box or flat structure to adapt to different types of goods. This design makes the full draw bar trailer more flexible and suitable for a variety of cargo transportation needs.

The suspension system design takes into account the relatively independent movement of the body, which requires a more flexible suspension system to adapt to different road conditions.

Due to the independent body movement of the full draw bar trailer, the steering mechanism is relatively simple to ensure that it can be flexible when turning.
