I will now go and read chapter 9, Commercial Vehicals; Aerodynamics of Road Vehicles, Volf-Heinrich Hucho, to see what I can learn about the void...
Up at the Aero Forum,under the thread 'Full-Boat-Tail Trailer for T-100' you'll find some graphical drag tables derived from wind tunnel analysis which cover 'gap-drag.' Some of the tables I derived from composite tables Hucho published.You don't have to measure or calculate anything,just look and read Cd. There might be something of interest to you there.
