Also realize that the aero wake/shadow of the tow vehicle has a top view. The template is fit to half the width so it tapers in pretty quickly. The shadow is also only that size if the gap was filled. Air moves in even faster than the template unguided, as it tumbles around, making the shadow area even smaller.
