I don't have a reference other than my 2001 2wd Super Duty, but it rides far better than my old one. I will say on wet streets, it breaks the rear tires loose easily, and has an annoying amount of wheel hop.
I can only compare it to my 2009 Ram 3500. The Tremor rides very smooth. I don't feel every crack in the highway. With offroad being the focus, Ford gave it a softer ride. My Dodge on the other hand, well it rode like a log wagon. Stiff as hell.
I have noticed that there are ways that it rides better than my chevy 1/2 ton. General road comfort is actually quite nice. The sharp elevation changes of very rough patches of road are where I notice that it rides rougher. Overall I think it rides nice for as big of a vehicle it is.
No warning yet. But I did get a warning that I was too tired and need to pull over when I went over the lane marker a few times due to a crosswind. That one caught me off guard. I was waiting for a too drunk to drive and engine shutdown next.
