Not sure I have much to add other than to suggest that with its longer wheel base over the Escape/Bronco it should ride better. I would expect the ride to deteriorate somewhat with the FX4 package, but hard to know for sure at this point.
I don't believe those that have been fortunate enough to drive or ride in a pre-production Maverick are in any position to share their experiences. We will all have to wait a bit I'm afraid.
