Before you try to mount anything, look at all your options. Monoprice sells very good quality and reasonably priced mounts of all types. Some clamp on, some bolt on, and there are many different types of mounts for all applications.
This is the bracket I used because our old HTT had a fold down TV shelf and had to be removed fro travel. Note it's listed under "Home theater". When I bought it was listed under "monitor clamps". So really poke around to see what they've got. Turned out it works great in our current HTT. I use a piece of velcro to hold the clamp arm away from the fridge door. This obviously might not work for you or be what you want. But I wanted to give you something to get you thinking creatively. Meanwhile make sure to get the info on the walls from the manufacturer as was suggested.
