On the front HCV, it is incredibly sensitive to adjustment because the control arm is mounted on the sway bar and not the actual suspension. There is a huge multiplication factor. A 1/2 inch adjustment on the front may actually result in a 2 inch difference in ride height.

Always measure ride height after lowering the coach and allowing it to come back up in travel mode. Any other method, such as having the coach all the way up and allowing it to settle in TRAVEL will product nonrepeatable measurements due to the hysteresis in the HCV.

I remember you telling me this or reading one of your posts. A very important concept to remember. I was going to add just the sensitivity part. 
Thanks for adding this Richard.
