If you've noticed your living room TV on 2015-early 2016's is a bit wobbly if you grab hold of it, you can only imagine what it does traveling down the highway. While I was installing a Samsung sound bar, I added a 1' X 4" piece of wood between the wood that the TV mount is screwed to and inline with a stud in the wall. I used a Kreg jig for the back screws. It doesn't make it rock solid, but it sure tones a lot of the movement down.
