Need help with TV replacement

X2 on heavy to take out, I found that staples in our area will recycle TV's for free!! I waited several years before replacing the front TV. The hardest part was trying to decide which way to go on a support system. I finally just installed a 1" thick by 10" high pc of plywood across the opening to mount the flat screen on. I used 2ea 1-1/2" vertical Alum angles on the sides of the TV cabn't to mount the wood pc too. I just recently installed a Winegard Traveler dish to replace an obsolete KVH dish on the MH roof. It was a bit costly but worth every penny since my wife and I use TV for most of our nightly entertainment while winter camping in the warmer southern climates!
