Any suggestions. I have a 32 Sunsation and would like to mount a 22" tv on other side of head wall. Don't want to make a mess. What about upholstery ripping when drilling through? I take it bolts go behind mirror? Any suggestions would be appreciated. Also what mount does Sunsation use?

We have mounted 15" screens on a swing arm mount in that same location. The bolts were hidden behind the mirror in the head. There is about 3/4" thickness on that wall. When drilling through the vinyl it sometimes helps to run the drill in reverse and push a little hard to get the hole started then run bit forward. Some of the boats also had a spare 12 volt power wire in the head cupboard tied up behind the switch panel. Hope this helps.
