I love the rearview mirror, too! There is a blind spot behind me that the side mirrors cannot pick up. The rear camera doesn't either, as I have it set to view fairly close to my bumper to assist with backing into places. The rearview mirror helps me with that blind spot, although it took awhile to get used to what I was seeing and where it was. I also rely on the compass on the mirror when selecting a camping spot. If it is hot and sunny, I like to park with my nose facing East, if possible. Gives the hot midday and late afternoon sun less surface and window area to bake me!
