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.
I picked mine up two days ago. I like the ride. I only have a few hours behind the wheel so far but It seems pretty smooth to me. Not much road noise and it seems to handle well. My wife and I both like it.
