Joel,
I would be surprised if you had what HWH refers to as "The Active Air System", the brochure is dated 2013 and I though that it was a relatively new offering. It uses a lot of computing and electronic controls and valves to manage the coach while driving. It even has a steering sensor so as you turn it anticipates lean and compensates for that, very sophisticated. As an example from their literature...
For example, when driving a straight, flat road, the
settings remain comfortably soft. But when cornering,
the system automatically reduces roll by increasing
outer air spring inflation and reducing inner air spring
inflation, thus maintaining a soft, comfortable ride.
