Plot hole: When Swayze goes through the weigh station, he is told he is exactly 80000 lbs in the US for a tandem tractor/trailer, (which is the legal limit, unless he has a permit, but unlikely to be EXACTLY that weight due to fuel burn, weight of driver, tools, etc) and sent around to have the load inspected. In 11 years of driving I have NEVER had a scalemaster inspect a load inside a dry van. Customs agents do, but not scalemasters. Also, Swayze tells the scalemaster he doesn't know why the pit bull is there, as he just picked up the trailer. That excuse wouldn't fly with an official. Finally, the way the trailer is loaded, the load would shift all over the place, probably not making 100 miles before being destroyed.
