I bought this system for its versatility. One camera is mounted on the back of the tractor to help with connectivity and one on the back of my RV to monitor traffic behind me and when reversing in tight residential areas. These cameras are NOT made out of a cheap plastic body. They are durable with metal exteriors. The monitor is large and is best suited for large SUVs, Class A tractors and motorhomes as per the description. Multiple ways to mount the monitor with the included metal bracket, the included rotating stand or the suction cup will be provided free of charge if you contact the seller. Pairing the wireless cameras was easy. The monitor menu is colorful and makes pairing and other settings easy. The WiFi range was excellent. The 1st camera is 20ft away from the monitor and the 2nd 40ft is installed at the back of the RV. No loss of signal or clarity. This company's customer service is quick to answer any questions and will do whatever it takes to ensure you are happy with your purchase. Update: Still works fine. The cameras deliver excellent color images on the monitor. The attached photo was taken under cloudy skies but still shows the color. Shooting in sunlight is exceptional.
