Decide on a location for your wall mount. Since your new big screen will take up a lot of room and weigh a considerable amount, you're going to have to find somewhere that will safely hold it. Screwing a mount into an RV wall is not a great choice, since the walls are typically made of vinyl or fiberglass. Choose a place with wood, metal or some other sturdy material, then measure the area to make sure your big screen will fit. Another option, if you can't find any shelves or upper areas to place the television, is to use a desk or table surface.
Purchase a television mount with an articulating arm, so you'll have the option of moving the television around. Companies such as TV for My RV (see Reference 1) make wall and desk mounts that work well in RVs, but most electronics stores provide them as well. When you purchase your mount, you should also buy a locking knob to keep the television from swinging around while you're driving.
Install the mount onto the surface you've chosen. Each mount is slightly different, but this typically involves screwing several screws into the mounting surface and then attaching the wall mount. Your television may come with a slide-on mounting feature, or you may need to secure a mount onto the back of your television as well. Then bolt the wall and TV mounts together to mount the TV. Be sure all screws or bolts are secure before moving on.
Slide your television onto the mount, using the help of another person if need be. Before you leave the television on its own, check to make sure the mount is holding the television properly and is not coming off of its mounting surface. Connect your television to the RV's power source.
Test out the wall mount's articulating arm to determine the best position for your television during viewing times.
Secure your locking knob to the television when the RV is in drive mode.
