I changed my TV in the Bedroom to a larger TV and replaced the mount with "Travel Mount" it pulls out and swivels. It also comes with dual mount so you can install a second mount somewhere. It was easy to install and came with the hardware needed. It is really solid. I did install a strap to further anchor the TV while traveling (just my peace of mind). I purchased mine at my local RV dealership parts dept, but you can get it at Amazon.
