If those are your measurements, leave it alone.

Especially if you are having an alignment done. Any changes made to ride height after alignment will change the alignment.

If you feel you must make changes to ride height, do it before alignment.

I would ensure the labeling on the wires is correct now. I have CRS, and something that was so clear today, is total amnesia tomorrow.

Glad it is back in order.

Print the manual I linked above. I know it says Prevost but it’s the closest thing I have found to the coaches you and I have. Also print this one. https://www.hwhcorp.com/ml20635.pdf

Take the time to read them and reinforce what you learned during the troubleshooting.

As Adam said, the Newell air system fundamentals are different than what most RV techs, and diesel mechanics ever see. It’s best the owner knows the system. I have had RV techs disagree with me over the phone and actually rewire the system based on how they thought it should work. In one case I spent a day with the owner undoing what the tech did.
