Well, finally got the TV off the wall this weekend, and it was not fun.This is similar to what what the bracket looked like:
The main problem was there was a release lever on both of the vertical brackets located towards the bottom of it. This became a problem when I had to reach the release levers (at the same time) from the top of the TV. So, standing on a 3 step ladder, with my face against the camper for balance I was able to release it and not drop the TV
Hopefully this will help someone else in the future.
