TV Mount on outside of Trailer

This is what I did. Mount is all aluminum and I used stainless screws. I drilled clear through the wall and installed a wood backing that is screwed/liquid nails to the wall. The area is under the kitchen cabinet and completely hidden. The mount is very solid. I used Non Sag Dicor to seal both holes and around the mount. The mount did have a cord keeper/hook on the bottom that I used a cut off tool to remove. Much cleaner look. I also installed the cable connection as well that ties into the power antenna/cable connection like all the other drops in the trailer.
