Our 2005 Providence is leaning to the passenger side - about an inch.  Camping World said Spring was bent.  Spartan repair shop says spring ok - but lean is causing driver rear air bag to be fully opened while sitting still.  Thought a block in leaf spring on Passenger front would correct. It helped a little.  Brought to 1/2 inch, but driver rear air bag still fully opened.  Coach is nearly empty except for water and fuel tanks.  Shop is going to keep working on it.
