Go too far back and all the wind off the truck just pushes on you.

But I did it before. 21mpg going 70 towing a 5000lb trailer!

well no chit sherlock, so does the wind from just driving in a lane on your own. simply saying you don't need to tailgate up the *** of a big rig to see a significant improvement.
