ABSTRACT:
Improvements in a trailer hitching and tracking steering system are disclosed include a new style RV or wagon style RV that includes an extendable, variable position tow bar that accommodates misalignment of a tow vehicle. The tow bar can be rotated for storage within the RV wagon. Further improvements include a wheel steering mechanism to improve tracking of a towed vehicle using a bi-directional caster front suspension for steering a wagon style RV in both a forward and reverse direction. The caster of the front wheels is automatically re-directed depending upon the direction of travel of the RV. The suspension system includes a steerable rear suspension that minimizes the amount the back wheels will cut the corner when turning. The improvements also include the use of visible light beams to guide a tow vehicle backing up to an RV to be correctly positioned for hitching without assistance.
