A machine includes a first cylinder coupled to a first wheel and a second cylinder coupled to a second wheel. A first proportional dampening valve fluidly connects to the first cylinder and a second proportional dampening valve fluidly connects to the second cylinder. First accumulators are fluidly connected to the first cylinder and the first proportional dampening valve, and second accumulator(s) are fluidly connected to the second cylinder and the second proportional dampening valve. Additionally, a first proportional flow control valve fluidly connects to the first cylinder and a second proportional flow control valve fluidly connected to the second cylinder. An electronic control module (ECM) communicatively couples to the first proportional flow control valve and the second proportional flow control valve to adjust a ride height of the first wheel via the first cylinder and a ride height of the second wheel via the second cylinder.

A recreational vehicle includes a frame, left and right air suspensions, a front jack, a tilt sensor configured to measure lateral and longitudinal tilt data associated with the frame, and a controller. The controller is configured to receive the lateral and longitudinal tilt data to thereby level the frame laterally via operation of the left and right air suspensions and level the frame longitudinally via operation of the left and right air suspensions and the front jack. Methods for performing a leveling operation include utilizing left and right air suspensions of the recreational vehicle in combination with operating a front jack of the recreational vehicle until the recreational vehicle is level along lateral and longitudinal axes.
