I have two RAM mounts for my PN-40, and both work really well. I have the tube mount bolted to the A-pillar grab handle in my Tacoma and it is very sturdy. If you grab the mount and move it back and forth, it moves the whole pillar. I also have the suction cup base for using the holder in other vehicles, and I just move the arm + holder from one base to the other. It's definitely the strongest mounting system I've seen; way sturdier than the ball-type mount that came with my Garmin Nuvi.
