No. It means...
It was the dark of the moon on the sixth of JuneYup. Convoy Day!
And a Kenworth pullin' logs
Cab-over Pete with a reefer on
And a Jimmy haulin' hogs
We's headin' for bear on Eye-one-oh
'Bout a mile outa Shakeytown
I says, "Pigpen, this here's Rubber Duck
And I'm about to put the hammer down"
Facts about Convoy...
...There was no C.W. McCall. It was a pseudonym for Bill Fries, who cowrote the song with Chip Davis. (Yes, THAT Chip Davis!) And then there was the film that starred Kris Kristofferson and Ally McGraw and directed by Sam Peckinpah (yes, that Sam Peckinpah.) I haven't seen it in more than 20 years, and I don't think I want to see it now for fear that my general good feeling about it will dissipate in a cringe.
