A manually operated leveling system for a vehicle such as a recreational vehicle or the like in- cludes three jacks in the form of hydraulic cylinders mounted to the vehicle frame. A shoe is mounted to the piston rod of each jack. Two jacks are located adjacent the rear of the vehicle and one jack is located adjacent the front of the vehicle. A series of manually actuated switches, oriented in a diamond pattern, are located within the interior of the vehicle, and are interconnect- ed with the jacks to provide selective extension of the jacks in order to adjust the attitude of the vehicle relative to level. A cross-check level or bullseye level is mounted within the interior of the vehicle for viewing by the operator to determine the attitude of the vehicle relative to level. A series of control valves are inter- posed between the jacks and the switches for controlling extension and retraction of the jacks in response to manual operation of the switches. A unique jack con- struction allows the jacks to be mounted to the frame in any satisfactory location while preventing interference of the jack springs with portions of the vehicle's under- carriage adjacent the frame.
