It also depends on the trailer design. Moving companies often use the small wheeled trailers that have a much lower floor. Those create a reasonably different air flow due to the rear being lower to the floor. I remember distinctly following one of these from Boise, ID to SLC in a '77 tradesman 100 van (318 v8). We got well over 40 mpg and could physically feel the pull from the "vacuum" being created. We were way to close to the trailer, of course, but not closer than 4-5 car lengths. Regular tractor trailers don't seem to produce anything but disturbances that make the ride uncomfortable.
