This is our Cross-View Mirror which mounts to the upper left corner of the Sprinter. When you are backing into a parking spot or loading area, you can see if there is a person or obstruction immediately behind your vehicle. Obviously, this can save you a ton of grief and money by avoiding mishaps in the first place. The mirror kit is constructed of all non-corroding materials, and comes with a large, 8.5 inch mirror head. One model fits low top or high top.
