Your first picture was taken on "Hollywood Hill" at Brad Wike's Southern Classic show in Lincolnton NC. One year he had the Bandit truck and the Black Mack "Rubber Duck" up there too. All 5 or 6 popular Film/TV trucks.
The brown Peterbuilt? tanker starred in some American movie about drug smugglers who had dissolved cocaine or something in petrol. (gasoline to you, Brocky45) The baddie driving crashed off the mountain road and it all went up in a huge fireball.
Some sort of modern "Horse opera." (western movie) Just slightly more exciting than watching grass grow.
I have my shoulder to the wheel,
my nose to the grindstone,
I've put my best foot forward,
I've put my back into it,
I'm gritting my teeth,
