I thought (briefly) about this too, but I bet what truckers have to go through on a normal basis would be enough to quash any romanticism about the occupation. Driving a big rig is not like "setting cruise control and heading down Route 66..."
Think about lugging a tandem trailer through 18 miles of a bumper-to-bumper construction zone, or navigating said tandem trailer through winter conditions in Utah, Colorado, Tennessee, or eastern Pennsylvania, for example. Even the same route, several times per week--even in good weather-- through the Great Plains would bore me to tears after a short while.
I remember that Karl Malone, shortly after he retired from basketball, moved to a truck-driving career. IIRC, he chose very selective routes (those in which he had an interest in driving), and then added a premium for his name recognition. That'd be the way to go.
I actually have done a LOT of cross country driving by car and noticed what they go through. I also worked for a guy that owned three Peterbuilts back in 1973 as his repairman and undloader. I abandoned it as a career when I started listening to the stories the truck drivers told.
I am a lot more mellow about this stuff now, but it’s just something that crossed my mind.
