Hi - Early last summer, while dicking around replacing a leaking air line connection on my passenger side, I'd loosened and moved the height valve to get the stalled inflation going again. Whether I should or shouldn't have done that, well, IDK. Keep in mind I was still pretty green in things GMC at the time.

After I buttoned it all up again I started wondering how the coach knew when to quit inflating/deflating when the level controls were set to travel. Still not clear on that BTW, but sure it has to do with the position of the valve/arm, just not squared away on how to set it up.

ATM, I have shut-off valves on the bags (OEM bags) and set the rear travel height manually using a measuring stick at the bogeys, then lock the setting by closing the shut off.

It works and the coach drives fine, but I'd prefer to have it adjust automatically.

The compressor is the OEM one but it works well. I have no air leaks either.

Any tips or explanations on getting this set up properly?

thanks guys

Larry
