Nice setup, Pat. I didn't see any vibration from it, either. Just don't get caught with the screen open so you can see it. It's against the law to have a video screen in view of the driver. Just today, the driver who brings Mel's oxygen was given a ticket. First, they stopped him for speeding, then when they saw the video screen, they wrote him a ticket for that, too. This is a big box truck and he explained that the screen was for the backup camera. The officer said that when he's not backing up it should be turned off.
Since mine sits behind me, I hope I can get away with it if I get caught.
