This is actually our 3rd TV on our 380. Marine life limits a TVs life!. Our flat screen TV is mounted on the port side of the forward bulkhead. There is an 18x21 base that is trimmed out and mounted on the bulkhead to control the connection points on the bulkhead. Then an articulating arm is attached to the base.

All cables are hidden inside teak U trim to the satellite dish controller mounted to the wall with velcro.
