Neat idea, but not needed on any regular vehicle IMHO. If you can't back up accurately to a trailer, you need to practice and probably not tow anything. I can see this being useful for an RV or something like that, but with our short little trucks, any trailer you are hauling you should be able to move the trailer by hand enough to make up that inch or two you might be off.
It would be cool for viewing truck position on the rocks though:
"You are on a ledge right in front of a big rock" Hand them the camera, they can then show you what your stuck on:)
