I understand cautious, I oversaw a fleet of 4xx vehicles. A personal vehicle outfitted with the backing alarm used exclusively in your driveway public or commercial parking lot is one thing, it's a completely different animal when you take that vehicle into a congested RV campground where peoples RVs are a few feet apart - side to side and across the road....sleeping, talking etc. They will not be thinking how neat your alarm is....whether the white noise one or not. IMO use those mirrors and camera.

I have sensors on mine that tell me if vehicles, kids, bicycles etc. come into any of the zones. If you don't have them the camera, mirrors and attention will keep you out of trouble.
