I have a Vizio P65-F1, looking for a wall mount that extends the most (full motion) has to be at least 22"

I know where you can get one with a 31.5" extension and handles up to 154lbs.  I have used many of these mounts and they are VERY strong.  Not the thinnest of mounts at 2.8" but it can handle up to 100" displays.  Message me if interested.

I have Kanto for my “55 and it is very sturdy and flexible. I did a fair amount of research and was very suprised at the quality of parts, ease of installation and strength of the main arms.

I've been using this one for about 2 years, on my LG 65"   
Very happy with it. I can turn the TV very far to right or left, and adjust tilt to minimize room light reflections.

I've had this one for nearly 10 years now, no complaints at all.
