Way back when, I thought a 238 Detroit was a big horse. Probably part of the reason I drive 46 mph?I am glad you pointed that out. Every year there is something new on the tractors, usually emission controls or electronic safety features. I did not envision today's trucks when I started working for a freightline. I would have never thought a fault code on a tractor could be diagnosed from a shop hundreds or even thousands of miles away. Or that an onboard camera could be accessed from the same distance. An old brain doesn't process new advancements well but I enjoy attempting to do so.
