Sorry,just joining the party.
Hucho has a whole section on commercial vehicles.The shots of the rig will help to see if there's something in the public domain you can borrow from.
I'm guessing it's a tongue-pull seeing that your going to do a topper.
Getting the trailer to "draft" behind is the key.Match tow rig back with frontal area of trailer front.
The gap between the truck and trailer can be 20% of the drag.Filling that in will pay you back.
If the trailer fenders protrude out into the airstream,they could be streamlined fore and aft.
Will wait to see pics.
