Hello I have a 2012 29.2 on F53 chassis. I had a lot of stability issues and white knuckle driving.
I read a post on a site about the stability bars under the rv and how there are 2 holes Currently the mfg uses the end hole. So I un-bolted the connection and move them to the rear hole. You need to do both sides and may need a jack to lift them.
This took care of many problems. See attached picture
I have done this to both the front and rear.
