We have a 2006 country coach. The HWH leveling system works fine manually. The automatic version is out of wack. I have not tried the adjustment because: The 12v pump (made by PARKER for HWH ) that supplies the air needed has the following problems: attached to the glass bowl is a ?solenoid? that has 2 wires. This "solenoid" is too hot to touch. When I disconnect the + wire it cools off. This system runs on the house battery and drains the house battery over time. Also when I loosen the pump from the mounting bracket (2 bolts) I get a heavy duty shock and serious sparks flying. Has anybody had this problem? We are coming to Madison and hope to talk to HWH.
