I’ve had my ‘18 Raptor for about 11 months and 9k miles now. I came from a Tundra which was leveled and had 33’s, and maybe I’m just lucky, but I have found my Raptor to ride much smoother than the Tundra did, so opefully your vibration is just a tire balance issue.
As to the steering, I will say that at first, it seemed like my Raptor wanted to wander on the highway, but I don’t notice it now, so I don’t know if I’ve just gotten used to it or if the suspension settled a little bit. FYI, Mine did not sit before I got it. I special ordered it and picked it up the day it arrived at the dealer which was only 11 days after the build date.
