33. A system for powered trailer weight distribution, comprising:
a hitch mount having a spring bar;
a trailer;
a spring bar mount disposed on the trailer and having an initial position relative to the trailer, wherein the spring bar mount is configured to receive and engage the spring bar;
a weight distribution actuator configured and arranged to adjust a position of the spring bar mount relative to the spring bar while engaged with the spring bar, wherein the weight distribution actuator is connected to a power source that provides power to the weight distribution actuator, facilitating the adjustment of the position of the spring bar mount, and wherein the weight distribution actuator is pneumatic;
a sensor configured to identify a status of the weight distribution actuator; and
a remote device in communication with the weight distribution actuator, wherein the remote device is configured to activate the weight distribution actuator, and wherein the weight distribution actuator includes a logic unit configured to receive information from the remote device, and wherein the remote device wirelessly communicates with the logic unit;
wherein the weight distribution actuator is further configured to adjust a position of the spring bar mount based at least on the identified status of the weight distribution actuator.
