The 6-pack supplies air to the HCV's on a full time basis and only controls the output of it via the "travel" solenoid valve which is open whenever in the "travel" mode. Therefore, it is possible that mechanical damage to the HCV could leak compressed air without effecting the level of the coach, it would just result in higher air consumption.
