Wrong clip for the film
This is the correct, & much better, (film) version
The sound of that RS700, as he changes down, just before the crest
SWMBO had a liking for Kris Kristofferson, how he looked here (& at that age; 42, when the film was made)
Another trucking film (second highest box-office receipts that year, after Star Wars, apparently)
Jerry Reed was also in the film; 'Snowman'
