I believe towing mirrors are a legal requirement in most places.
Specifically, you have to be able to see what's behind your trailer, not just your tow vehicle, so you really need extension mirrors that move your viewpoint further out.
(And yes, you do have to remember to retract or remove them when you're parking. Dont ask me how I know... :-)
Blind spot sensors would be useful in addition to, not instead of, mirrors.
