Here is what I ended up going with. I will let ya'll know how well it does or doesn't work. The camera met what I was looking for, that being 170* view, a built in measurement graphic and Waterproof Night Vision Backup Camera. Here's the link: http://www.amazon.com/gp/product/B0039667A4
This is the monitor made specifically for back up cameras: http://www.amazon.com/gp/product/B005CFLMNC
Both had good ratings from buyers and as you can see came from Amazon who has a great return policy if not satisfied.
Hope this helps!
