When AJ and Ruby look at the pinup calendars in the auto mechanic shop bathroom, they are all real life pinups of guest star Adrienne Barbeau who plays the mechanic's wife, Helen.
Perhaps it's unintentional but there are several parallels to the Australian film 'The Adventures of Priscilla, Queen of the Desert'. Besides the obvious - drag queens, RV, small regional towns - the mechanic in this episode shares his name - Bob - with the mechanic of Priscilla.
