Trailer vehicle

A trailer includes a wheeled chassis (100) and a tilting bed (104) mounted on the chassis (100) for pivotal movement between a rearwardly inclined loading position and a forwardly pivoted, horizontal loaded position. A tailgate (107) is hingedly connected to the tilting bed (104) and is movable between a loading position, in which it forms an extension of the bed (104), and a substantially vertical position.
