anyone installed (cheap) wireless backup cameras on 30+' trailers, with (+) results

Thought it might be beneficial to have a camera mounted to rear of trailer, but would want wireless (for video signal) as rca wire would surely get damaged, or just corroded from sitting. Additionally running signal wires into tow vehicle(s) not worth the effort for me. So has anyone installed a wireless (not counting power/ground) cameras to their longer trailers, with good results, and which cameras did you use? Thank you and advance for all who help. Willing to used included monitor, or my vehicle's nav screens can take an rca input if the camera just sends a signal to a receiver that converts it to rca jack.

Don’t have one myself, but they make battery operated wireless camers that you can access with your iphone. Sounds nice and simple, and easily movable

Not necessarily cheap, but I have one of these I used to guide myself into a 5th wheel camper when I had one. Then I'd stick it to the step bumper when backing up to my tag along trailers.
But it's been sitting unused in a rear door pocket since the last 2 trucks have had factory back up cameras.
