Haven’t noticed whether it sits down quickly after parking. I will check, including for hiss. I know the bags deflate overnight. thanks for your comment.

I have a 2003 National Tradewinds coach. Cat diesel and Allison trans on a Spartan chassis. The rear passenger side rides a few inches lower than the driver’s side. May be the ride height valve. Not sure. Also, coach “sits down” overnight (airbags deflate) without my dumping air. Any ideas on whether it is a bad ride height valve or another leak in the air system?
