To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
I originally purchased camera and monitor set for our travel trailer, installed and worked awesome. Since I also had a cargo trailer, why not install a camera there too? Ordered this camera and used original monitor, all works great!
