I used this to mount a 32\ TV under the bunk in my semi-truck. I screwed a few planks into the upper bunk frame and then mounted this to the planks. I have been pleasantly surprised how well it has worked. I had expected that I would need bungee cords to help keep the TV in the up position while driving on bumpy roads but not so. The ideal viewing position would be a little further away so I plan to implement a slider at some point."
