I tried it and the signal was weak. Also, it seemed as though trees, oncoming traffic, billboards, etc would cause a severe degradation of the signal. I wound up running coax from the rear of my trailer to the hitch area (I tow a 5th wheel) Next to the trailer connector in the bed of my truck, I added a "F" connector and continued hard wire up the my dash area. Bought a flat panel monitor off e-bay and video is good. One problem is that the picture on the display needs to be reversed so it isn't too confusing. Without reversing the picture, if you were to see a car trying to pass you on the screen's right, it is actually trying to pass you on your left. A little research on the controller inside my monitor gave me the info to lift a pin and reverse the video. Now it looks just like looking in the rear view mirror.
