I've no data for trailers,but VW had a 'drop' form body,created by Rolf Buchheim and his associates in 1981 which is shaped like Varn's description of Delaire's trailer.
This 'car' had around Cd 0.16-0.15.Nothing is mentioned about directional stability in Hucho's book.
In Hucho's section on trailers he does mention that leading edge radii can impact yawing moments.
This trailer body type would make for a nice graduate,scale model wind tunnel study.
