TV Mount on outside of Trailer

I've seen those with outdoor tv mounts from the factory which they imbed a piece of solid material during the lamination process of the sidewalls in order to apply the mount later down the assembly line. Some rigs come with a swivel, articulating mount in one of their bays where a tv can be attached for exterior viewing, this would be a little easier to accomplish aftermarket since a piece of wood can be anchored to bay side wall before applying tv mount. Since the occasion to watch tv outside is rare for us we have just used a table to set the tv on. Maybe you could post a few pics after you have completed this project for others desiring this feature.
