Don't make the front of the trailer into a scoop that scoops air between the towing vehicle and the trailer.
Use a convex shape.
Don't use any circular shapes at the rear.
They'll destabilise the trailer.
Cut it off sharply at the rear, if possible with the sides / top / bottom plates extending a bit (2-4 inches) beyond the rear wall - i.e. forming a shallow box of thin plates around the tail end.
If you get around to covering the gap, the covers can rest on / slide over the convex front of the trailer.
