I only have one camera which is mounted on the back of the TC. I flat tow my toad, not a trailer. I can see my tow bar and behind the Samurai. If I could back up, which I cannot, the camera is high enough for me to see where I was going. I would have little improvement with an additional camera. I could adjust the camera down and see the entire hitch and two or three car lengths behind the Samurai. I prefer to see further back.
If you purchase your camera from a reliable source that is in the camera business, you have several options. I purchased from
RV Cams.
