A vehicle system and method includes a primary vehicle (PV) and an auxiliary vehicle (AV) selectively connectable to the primary vehicle. The PV and AV vehicles each having an ECU, a propulsion system a braking system, and a directional control system for steering at least one wheel thereon. The ECU of the PV and the ECU of the AV in communication with one another to form an interactive control system that control operation of the systems of the PV and the AV when connected to one another. The vehicle system also includes a docking system for connecting the AV and the PV. The docking system includes an automatic docking actuator that automatically connects the AV to the PV when actuated. Optionally, a remote control device communicates with the ECU of the AV for controlling the AV through the ECU of the AV when disconnected from the PV.
