Where to mount a TV in my Edge M18?

My wife & I bought a new Heartland Edge M18 that came without a TV and now we're planning to add one. The walls that are in the space where the bracket is supposed to be mounted feel very flimsy and it's questionable as to whether or not they'd support much weight (plus, I don't know what is behind these walls that could be damaged). The ceiling and back wall of the box are very sturdy but I'm concerned that if I put the bracket there it would penetrate the trailer's shell to the outside. Can anyone tell me where I can safely put the TV bracket?

Welcome to the Heartland Family and forum. This forum has a lot of people willing to share information.
You should get some information from other Edge owners. If not I will move your post into Ask The Factory.

Peace

Post a some pics of the spot where the TV mount is supposed to go. If we can see it we might be able to help a little more. If you can't then you might be better served under the ask the factory section.
