Hi. I have a 28" tv that I want to put in my cab. How should I mount it? My cab is NOT mdf. It's plywood. 3/8" I believe. The tv is old and extremely heavy. What should I do to mount it? Craigslist had no LCD tvs of the same size, so I guess I'm stuck with the monster I have. Should I try a shelf inside the cabinet or a whole new structure all together to hold the tv?
