Hadley system 450LXi

[dentmac]

Trying to learn what changes Hadley did to the Active Air system when they changed the tie rods, etc.
Obviously they added a solenoid to plumb the right and left front airbags together. This appears to be "Normally closed". When leaving the coach without power, you should leave it with the levelling system (SAMS) on as the solenoid is then off. With SAMS off, the solenoid is drawing enough power to be quite hot.
ie The solenoid is active in Drive Mode.
I understand that the levelling is done by the twist from the back like a 3 point system but what is used for the height of the front? Just one side? The wouldn't work well - In a corner when the outside suspension compresses--the leveller would raise the entire coach.
I'm trying to get a response from Hadley .
