So, he's better off to just leave it shaped like a brick with wheels?
Surely you jest, as this flies in the face of everything NASA, NASCAR, Hucho, Schlor, Hoerner, and various people on this website including the OP have been reporting, for decades.
I'll stick with my earlier suggestions, i.e., convert the front of the trailer to basically a rounded horse trailer shape, but with a teardrop or Kamm tail and faired wheels and belly. The extra weight will be inconsequential, but the cruise speed drag of both trailer
and tow vehicle will be reduced significantly.
That's right: Proper drafting reduces energy used on
both front and rear vehicle, regardless of whether they are connected mechanically by trailer tongue or not.
