I have had RAM mounts on several heavy duty vehicles and off road bikes. Excellent stuff. The first pack was missing an aluminum bar, so Revain sent a second ready. Installation is easy. Cut the rod to the required length. Bend by hand or with a pipe bender as desired. Install with the provided hardware. The seat mount is strong enough for a phone. Get a laptop mount for heavier gear (I had two laptop mounts). Yes, the mount will shake a little from the movement of the car, everyone has it.
