Rear View Camera for Race Trailer?

Just got a trailer to take my car to races. After driving it, I wonder if a rear view camera would be useful on the trailer? This would aid in backing and possibly as a mirror assist (the 22' trailer seems a long way back there)? Example: Any experience with this sort of thing? Thanks.
