I think it is a good idea considering that when you back up it is not always your wife(husband) back there. I doubt you would expect to see hams the only people willing to assist you back up.
And the FRS radio is a good idea, but you have to plan to have someone back there - with the two-way speakers it could be anyone - and change without having to worry about it.
It is also helpful for others in the immediate area to know what you are doing so they can watch out for you - well, for themselves...
