What you need to search is the "Cheap Handling Fix" by discoverer/inventor John McKinley.
I don't want to upset the moderators by linking you to another RV forum, but that is where you will find it.
I experienced much improvement from body roll by doing this. Others in the CHF thread will recommend the "fix," a rear track bar and Koni shocks.
With the CHF only, I went from mandatory two hands on the wheel for security to being able to drive 1-handed on the interstate if I choose.
The CHF is doable on chassis newer than the 1999 F-53. Some are just change bolt locations and some need link extensions. One is labor only. The other is a $100 expense. Either way, it's "Cheap."
