First decide where you want to put your monitor. The best place is on the dash or hanging above the windshield. The monitor needs to be in a place that is visible from the driver's seat. Be sure that the monitor does not block your driving view or cause a blind spot. It is best to put it in a location that will not distract you when you are driving either.
Most backup cameras are now wireless and are therefore easier to install. The best part is that you do not have to worry about access wires running throughout your RV. This also means that you will not need to drill any holes to hide or trail wires through your unit. Start by mounting the camera on the outside of the rear of the RV. Many people mount the cameras by the license plates while other mount them above the license plates to provide you with a wider angle. Keep in mind that you need to hook the camera up to your backup lights so the camera knows when to start recording.
Some units have a sound option as well. If you bought a unit that comes with sound, the best place to mount the microphone is by the license plate on the back of the RV. Microphones are useful because you not only have the co-pilots signal, but you'll also be able to hear them shout when you're about to run into something or over them.
