Todd, There are no lights or fans or ducts that would create an issue. The deflector is 6" below the deck so I only have 9" to worry about. I'm trying to not say exactly what this guy has said so that I can get other opinions before I influence anyone's answer.
If anyone else wants to throw in their two cents, that would be great.
