My wife and I work as a team. We placed a mark on a spot of the rear window that I can see from the rear view mirror. Wife stands next to hitch with her arm raised over the tongue(She trusts me...silly girl!). Then I line up the mark on the back window with her raized arm and slowly back up til she yells stop (if I hear her
). Works every time. She just cranks the tongue down and off we go.
