We looked at a used Tour that they guy had added the HWH Active Air system.
Active AirA bit pricey, but it does a couple of things as an aftermarket product for hydraulic level systems on rigs that have air suspension by tying into the air bags for your suspension:
- It enables you to level with your existing suspension air bags if leveling is within the capacity of the bags.
- It uses the air suspension to continuously keep you level down the road by enhanced sensor system tied to steering and load level switches so the bags will inflate on the outside of a turn to help level the coach.
I didn't know much about it at the time, but after learning it would have been fun to try it out.
