I'm not a serious off roader either. But from what I've seen you usually have spotters to help you navigate the serious stuff. So I can see how the cameras and sensors help in the hairy stuff.
As long as you don't mind being laughed at by real offroaders, buy all the "high tech" you can afford!
However, when it breaks or ends up being useless while offroading, expect the same wrath power windows, power locks, computer screens, etc. on such vehicles deserves!
