Does anyone have this (http://www.jpcustoms.com/store/customer/product.php?productid=16269&cat=704&page=1) backup camera system from jp customs? It looks pretty cool but I'm hoping for some feedback on it.

No, but my wife could use one.

I like the mount for the camera. I think I will get one once I repalce the radio. I want it integrated into the radio / nav screen. I did not want the extra monitor.

I need one of those cameras..I can't see with my big monster when I back up!

I've been looking for one like this, this is a much better price than I've seen elsewhere.
Not to thrilled about the low mounted camera though. That can be changed. Would prefer to mount it up high, like on top of the shell looking downward.
Some of our line trucks and troubleshooter rigs have the Obserview system installed. Works great and has really cut down on the backing accidents. Sure would help with hitching up a trailer! Thanks for the link!
