Well, I can not chime in on the full camera system and I never really felt I needed one. However, at some point I would like to add a back up camera. What I seen a lady do on YouTube was very clever. She bought a wireless back up camera and display screen. When she was backing up she sat the screen on her dash, when she was done backing up she took the wireless screen with her and set it up in her truck camper. Now if she gets a nock on the door she can see who it is before she opens the door. Plenty of strange people out there in National forest and such. Her wireless system was infa-red and she could even see who/what was at the door or in back of camper at night.
