Mounting a TV in the bedroom

[joe in calif]

I have a Jayco Jayflight G2 23FB. It came with a TV mounted in the dining area and a collapsible shelf for a TV in the bedroom. I don't want to use the shelf in the bedroom because with it up there is little room to get around the bed. On the other side of the bedroom wall is a cabinet so I guess if I bolt a TV mount on the wall the cabinet on the other side will hide the bolt heads. I know some of you have mounted a TV in the bedroom so I was wondering how you did it and if there are any support beams in the wall.
The wall I want to mount it to is the one in this picture on the left behind the couch.

I did mine exactly as you are describing. I rested a 2x4 board about 10 inches tall on the inside of the cabinet and ran my mounting screws through the wall in the bedroom into the back of the cabinet and 2x4. It seems very solid but I still take the TV down while traveling because it's heavy. I'm sure that others may have a better or more cosmetically pleasing method but I like Redneck engineering. In the bedroom you can only see the mount itself, and the 2x4 can only be seen when you open the cabinet. The wall is hollow so I was careful not to run it down so tight that it would crush the wall.

Thank you for the reply. I guess that is what I'll do
