No, you don't want to pierce the skin! You're opening yourself to eventual water damage, and seriously devaluing the unit by such a mod. Instead, find the wall studs (using a stud finder) in the area where you want the TV. Then mount a 1x6xwhatever, stained and finished, across the studs, using at least 4 wood screws through the 1x6, and into the studs. Then you can mount a TV mount anywhere on your new mounting board.
