So everytime the coach moved, the sensor would change it's position. No amount of recalibrating would have ever fixed it. I used large pop rivets to permanently reattach it to the mounting plate. I did not recalibrate it trusting that the factory calibration would be correct once the sensor was remounted. That fixed it. 2 years later, and it still operates perfectly.
Good information. Thank you!
