G'Day Stewie, Thanks for posting that link unfortunately the coloured illustration in that article shows a green area that must be visible behind the caravan - this would be impossible no matter what mirror you have (see pic and arrow) I think they've used an American illustration as well as the steering wheel is on the wrong side - Australian rules are not the same as American so I still don't know what to believe is legal!
Yes Murray. She would be great to have as a passenger when reversing into a tight space. Also when leaving a happy hour she could check out whether anyone was talking about you.
