Thank you, Richard. The extra details on that explain the 3 position switch as well.

Please support the coach, when you release the pressure on that valve, that side of the coach will drop all the way to the suspension stops it.

Yeah, there's definitely a reason I didn't pull it out to look for a part number.     And I think I'll lower the coach onto my cribbing before I even get under there to remove it.
