How do you hook up your 5th by yourself?

I look in the rear view mirror - not the side mirrors - and get the hitch exactly centered in the window. I stop before the hitch gets to the pin to check the height of the pin and adjust as necessary. Then I back up slowly until the hitch latches.

I need lots of help backing up so I don't run over or into something but hitching up is something I've always done solo.
