Also HWH is Bi_Axis leveling. That means 2 jacks are always going together to prevent twisting of the frame.
Powergear systems have different Auto types. The common system is the 2 front Jacks are connected thru a T and both jacks will extend to prevent twisting the front to keep from popping out a windshield. Doug
