Well I finally got the beaver out of the barn so I could get under it again. I learned a lot today. First, after getting lots of light under there, I found there are only two air lines connected to the leveling valves (thought there were three), so it is just a generic ride leveling valve. With that said, there is no possible way you can exceed the ride height when trying to level it for camping. All you can do is lower front, back or side. And once lowered you can raise the front, back or side up to ride height and that's it! So when I try to raise it manually or Automatically, once any one of the leveling valves reaches and tries to exceed ride height, the leveling valve begins exhausting the excess air that is trying to be put into the air bags. This exhaust air is what I thought was an air leak. It jus happens to be near where the air supply attaches to the leveling valve. So long story to short - the problem is not the coach but me hahahah. If I were to design it, I would have over ridden the ride height valve to maximize adjustment (Maybe newer coaches are this way). And actually more useful, I wish I could be able to raise the the rear (or front) in situations when the road, driveway or whatever situation arises when an extra few inches above ride height would prevent dragging or scraping since they have such massive overhang from the axles. I Welded a heavy duty roller to the ball hitch insert which comes in play many times. Thanks to everyone for chiming in.
