I have this one, has a different monitor, but they both use the same rear-view camera.

Seems to work decent, and several others have used them that I know of. They work real nice on the vintage motorhomes.
The rough bit with mine is you need to drill holes to mount the side cameras...good thing I'm not afraid to punch small holes in shiny aluminum trailers. (oooh, I'm gonna get flamed for that one!)
The one thing I didn't like is that the trailer to tow vehicle connectors SCREW together, and in the event of a busted hitch or other trailer disconnect, the cable is going to get broken if its a full breakaway. Trivial issue in the larger sense of an event like this, but it's the only thing I can come up with that's even a tiny bit wrong with the system...
