I was in a Kenworth pullin' logs

I remember that song from a K-Tel record of trucking songs that was advertised heavily on TV in the late '70s. There were a few years when trucking, CB radio, and Teamsters were very much in vogue (gear, movies, and songs). I'm not sure why - did it have something to do with the gas crisis? Or was it just the point at which the highway system was sufficiently developed that long-haul trucking, tollbooths, and radar speed enforcement first became a thing?
