Kacyk,
Check out the Unicam backup camera. It is the same as the regular hitchcam but you have a very small camera that you can mount anywhere you want to get the best visibility.
Here is a link to it on the trailduty.com website:

This is the route I a going to go once I figure out all of the A/V junk I am going to put in.
