I have the 2002 Monaco Diplomat 38PBDD. I noticed in my owners manual the ride heighth of 9 1/2" Front and 11 1/2" Rear. I was told to contact Monaco Tech. support for the correct ride heighth adjustment. They told me 9 1/4" Front and 10 1/2" Rear. I would set to Monaco Tech. Support Numbers. May want to call them again at 1-877-466-6226 to confirm those settings for your coach.
