Jason, What an awesome method and thorough description! Usually we leave out details like "leave the vac running" but details like that often make a HUGE difference! As I read it and mentally did it with you, I see maybe one detail to add: when you're screwing the board to the wall, remove any screws that you detect going into studs. That should be easy to feel.
A good answer is easier with a clear question giving the make and model of everything. "The biggest problem in communication is the illusion that it has taken place." -- G. “Bernie” Shaw
