You persist in missing the point Frank Lee? Less than ideal "wake separation"
with a 5% penalty is irrelevant with what is important in a travel trailer. Even a tripled penalty is offset by frontal treatment and edge treatment.
Show us the production trailer where squared rear edges match, must less outperform, the acknowledged ideal the past 80-years for all situations to be found on the road concerning winds.
Some other stuff:
A European trailer no longer sold here, but a good design, and pretty good reports from owners in re road manners (Leaks were another thing). The page points out design considerations worth knowing for a travel trailer.

An extended discussion in re aero from RV.net. Wes Tausend does a good job, IMO. (The contributors are other trailer owners with a lot of miles).

Trailer Life Directory Open Roads Forum: Wind Drag: V-Nose or Sloped Nose?
With both the OP's trailer, the BRENDERUP and the AWARD, the front is "V'd" (or splits the air) up & down versus right to left. Is it because of sidewall drag? Or construction/space considerations? Or does it matter?
