I think Phil was talking about the reduction that the template makes on a given frontal area, not in comparison to the truck without trailer.
The truck is ~34.5 ft and 0.44 cd, Cda of 15.18.
The trailer is at ~53 ft.
To get to an equal Cda, The assembly would have to get to a cd of 0.286.
The bulk of the truck's cd issues are the square back of cab and then tailgate.
I suspect that I will get a cd considerably lower than 0.286 with a little modeling help
