So the only difference in your d and 5.0 is the rear airbags?
Did you upgrade to comfort seats? Trying to understand how the two vehicles could feel so different.
I have the third row option do have the self leveling and never have thought the suspension to be jittery in the least. Maybe it makes more of an impact than I would have thought.
Congrats on your new ride.
