I searched the Toyota forums and consistently saw this item mentioned as one that would not move on bump roads or even over time on smooth roads. It is the best and must secure mount I have ever used. It fits perfectly on was designed not to obscure the view. I have recommended this brand to everyone that I have talked to about mounts since I got. Very easy to install also!
