Looks like you have a rear window. If you have a rear view mirror that can see the rear window. Try installing a Fresnel lens in the rear window. I have the larger one in rear window. Works very well for a quick look at our toad and checking for lane change clearance.
I put a Fresnel lens on my RV when I bought it to supplement the rear view camera. Then, 5 years later, I took it off and threw it away. I use the camera and the side mirrors exclusively. However, the Fresnel lens DOES work.
