I would think a standard flat mount or fold down mount would be best. On a interior wall you can use traditional fasteners if you can find the studs. You may want to use a piece of plywood for rigidity as most of the pictures in the article below show.
Flip through these pictures of TV mounts in RV's.
I might as well comment since a picture of my mount is used in that article.
I used a piece of 3/4" plywood that spans three wall studs. The TV mount is bolted to the plywood and the plywood is glued and screwed into the studs. The mount holds a 32" LCD screen on an articulating arm. It is rock steady.
