An adjustable length steering arm is pivotally connected to the sub-chassis and to the chassis forward of the connection to the sub-chassis. A system of linkages connects the forward wheel king pins with a mounting point which is rotationally fixed with respect to the steering arm and operates to turn the forward wheels from the steering arm so that the trailer tracks the towing vehicle. In a preferred embodiment the mounting point is moveable longitudinally to enable the forward wheels to be moved in the opposite direction during reversing of the trailer.
