We already had a Furrion "Observation" camera on our Bighorn, which allowed us to not only see while backing into a site, but it also allowed us to view traffic as we drove. Very helpful to see traffic behind us.
Now we upgraded to a new model from Furrion which includes 4 separate cameras and a 7" viewing screen. While I loved the idea moving from a 4.3" screen to a 7" screen ...it was simply too large to fit on the dash of our Ford F-350. Yet, as you can see in the picture below, we placed the viewing screen down near our cup holders. It is actually a great spot for viewing!
Having added the 2 side camera's and the new rear camera...we are in awe from the difference a few years can make. As you can see below, the rear camera provides a huge viewing area...we can even see our bicycles on the back of the RV!! When you watch the video....note the side views. The one down the driver side is fantastic, however we have a slight blocked view on the passenger side due to our awning arm. That is NO fault of Furrion, just an issue we have to work around with due to the awning arm.
