This short tale my help you diagnose a similar issue with your coach in the future. After the last trip, the coach would not reset to the ride travel height on one corner after I manually leveled it. Since I had recently installed new height control valves, I ASSUMED it was a HCV problem. So I spent the better part of an hour readjusting the HCV with no improvement. Still on the wrong track, I manually adjusted it to the correct height and it seemed to be OK. I next made the second wrong assumption, I assumed that something had caused the HCV to malfunction.

In piddling around with the coach, it still was not acting right on this corner. Then it hit me, a malfunctioning travel solenoid would keep the the HCV from working. Sure enough, the travel solenoid valve for that corner was not working, or opening. A quick fix and the coach is sitting pretty.

The moral of the story being that not all ride height issues are caused by the HCV.
