I don't have a recommendation for a camera to use through the rear window, but probably most any camera without night vision would work.
Here is an very good quality camera and what I have on my motorhome.
cameraIt is designed for exterior mount, and may not work well through your window due to the LED's for night vision. This camera has a threaded barrel type connector, and may require adapters to work with your cable and television. On edit, I just noticed that this ships with 32 ft of cable and an rca connector converter.
