My new 2010 f150 truck came with one and I agree with the same features you are referring too...
My center console screen is at least 7-inches and camera view comes up when I go into reverse. The view has feet markers with increasing beep alarms if something is in the path.
In my case I can see my BALL MOUNT go under the trailer hitch on first try. Don't know how I have got along without one over all the years...
I would want all of these features if I was looking for an aftermarker rear camera setup...
I used to see alot of rear camera professional setups on EBAY that truckers use for around $400 - $500. I would want to mount my rear camera high up on the TC pointing down at an angle to reduce outside light source from flaring up your monitor screen. Something like this google photo
