I installed a rear camera inside the spare tire housing on my 2604SS, it has a plastic spare tire cover. It has worked out very well. No vibration and good picture. It is wired into my factory nav system. When I shift into reverse or turn on the turn signals the nav switches to the rear camera. Or I can press the rear window lock switch 4 times to switch to rear camera. The device that enables this is called a GM Unlocker. I also have a camera above the truck license plate with an AB switch to switch between truck camera and TT camera. Makes hook up very easy.
