New trailer delivery question

There are dozens of transport companies in Elkhart County, Indiana. They hire drivers with their own trucks who transport trailers to their destination all over the U.S. I do see smaller trailers on flatbed trailers, 2-3 at a time. Motorized RV's are driven to their destination. I see husband/wife teams towing and driving rigs. One tows a toad so when they get to the delivery location, they can hop in the toad and return home. Elkhart Campground is often used as a staging area. Any day of the week you can see a dozen or so rigs sitting up front waiting to leave for their final destination. A former high school classmate of my DH's drives class A's across country to their destination. She's been doing that for years.
