Wow, driving a Kenworth sounds so cool! Your friend's truck with the sleeper, 10-speed, and that big Detroit Diesel engine must be awesome. I can just imagine how loud and powerful it feels, especially with you saying it's super comfortable because of the air ride suspension. Driving it around and feeling like the king of the world is such a cool experience! Thinking about quitting engineering to become a trucker shows how much fun you had. Trucks are really interesting, aren't they? Maybe I should look into driving trucks too!
