I actually mounted mine on the bulkhead closet (depending on your models yr, mine is a 98).  I used  a swing are with anchor ties on the bulk head. This allows me to watch in bed or rotate it to watch form the dinette.  There is more than enough structure to support the are and all cable / power was there for the old 12 v TV original to the boat.

It was also easy and clean to route the cables to the arm via small hole and a chrome clam shell vent cover to hide the hole.

Hope this helps!
