Hi. here is my set up to deal with the blind spots.
i have a 2016 xlt. van came with back up sensors and no factory back up camera
i added to first cameras above the license plate.
second camera to right rear trim. pictured below.
I added a 7" monitor with 2 av channels. av1 is the rear view, which i leave on all the time.
the picture is better than that. camera not focusing.
when I want to check my blind spot, right rear I switch to channel av2
it really helps when backing out on parking lots. i really don't miss having rear or side windows now.
