Yes I am reading to try to learn the system. My tag is in the center position on the dash. The left rear is very low when the coach sits with no air. When I hook the shop air to it 
and run the engine the coach air up however the left rear is still low. I am looking at the tire from the top if the fender. I moved the rod approx 1/2". Do I need to let it off the bags and rear it up? I could try to fully air up the tag. 

Thanks
David
