Gmt800 backup camera

[yz2009]

I've got a 2004 Sierra 1500 I would like to add a backup camera. I do a lot of trailering in the summer and it would really be nice to have a camera back there. Not to mention backing into parking spots without having to worry about backing over the tiny car in the spot behind you.

 

I've looked around but haven't seen too much for the gmt800's. I would like one that's on the tailgate looking down. I've seen some that mount behind the receiver but I don't know if I like that location. The only one I've been able to find is this one:

I was wondering if anyone had any experience with backup cams on an obs truck. Thanks
