JPJ,

This will require some investigation, but I suspect while the systems may in fact vary from converter to converter and from model and year to model and year, I think there are going to be some generalities that we might be able to make that will help almost all of the POG attendees. (Obviously I have a Liberty to use as my learning tool, but I know guys. And these guys can look at their CC, and Marathon, and Royale, etc. and we can all compare notes.)

I say that generalization because when some converters create their own variations, they appear to not alter the valving, as much as they create an additional electric system that piggy backs on top of the Prevost provided leveling controls. When the coach is in the "automatic" or self leveling mode that switch position just takes the manual controls from the Prevost circuitry and the automatic circuitry becomes the control of the valves via the solenoids.

The more we dig into this, the better our understanding of the variations will be.
