I sometimes hear some strange noises, but not to a point where they are annoying. I think it's due to the truck being so damn quiet when driving, you can hear a feather fall.
Yep get it on the truck and our 2020 X. Best I can tell it is geo location data telling the rides to adjust the suspension due to the location which causes them to be more active than normal. I say that because both rides do it in the same spots and I see the message the suspension being adjust due to location. I know they added that a while back, if a road has horrible potholes or rough areas that other vehicles had recorded Tesla uses that data to help other vehicles adjust before you get there to make it a smoother ride.
