I am about to install the rear camera and would like to know if anyone attached the camera to the plastic siding instead of the rear window. If yes, are you happy with the decision and is it holding fine on this surface. I am a little concerned of sticking the camera on the wire heater pellicle (potentially damaging the pellicle if/when removing the camera). I may also be purchasing a Rear Liftgate Sunshade and was wondering if the image quality of the camera installed on the plastic siding is greatly affected by the Sunshade.
