A lift assembly includes a lift arm having a first arm portion, a second arm portion, a first actuator, and a second actuator. The first arm portion has a first end coupled to a chassis and/or a body of a vehicle. The second arm portion interfaces with the first arm portion and terminates with a second end. The first actuator facilitates repositioning the second arm portion relative to the first arm portion. The second actuator facilitate pivoting the first arm portion about the first end. The first actuator is configured to reposition the second arm portion relative to the first arm portion when the second actuator pivots the lift arm between a stowed position and a working position such that a relative distance between the first end and the second end changes as the second actuator pivots the lift arm between the stowed position and the working position.
