1. A vehicle, comprising:
a chassis;
a mixing drum rotatably coupled to the chassis;
a fill level sensor configured to provide a signal indicative of a fill level of a material within the mixing drum;
an axle assembly coupled to the chassis and including a first tractive element;
a suspension actuator coupled to the axle assembly and configured to apply a biasing force that forces the first tractive element into engagement with a ground surface;
a lift axle coupled to the chassis and including a second tractive element;
a lift actuator coupled to the lift axle;
a location sensor configured to provide location data indicating a location of the vehicle; and
a controller operatively coupled to the fill level sensor, the suspension actuator, the lift actuator, and the location sensor and configured to:
calculate a target weight to be supported by the first tractive element;
control the suspension actuator to vary the biasing force based on the fill level of the material within the mixing drum and the target weight; and
control the lift actuator to reposition the lift axle based on the location data.
