I had replied earlier however IRV2 intercepted it I was not aware that I could not reply directly to you
1st I made an error in the link to many "W's" try this one:
Not sure what your coach is like. I replaced ours several years ago.What I remeber is: In each overhead (front left & right) side cabinet there was a bolt that held a metal strap that went over the top of the TV, after removing the strap the TV can be lifted out (be careful very heavy)TV was plugged in the right overhead into the inverter. In my coach I removed the plate (vinyl covered) that goes over the inverter on/off switch & the TV signal switch box. Then I removed the shelf that the Inverer rests on (equipment was secured to shelf with indusrtial velcro). This clearing of the right overhead gives you more room to work. My solution was to reinforce the mounting area & install an "Articulating Wall mount". The mount was putchased on Ebay around $40.00. Again in my coach the VCR/DVD & the TV plugged into the inverter & the inverter plugged into the 110V receptacle that is built into the right overhead cabinet.
Good Luck with your project.
