Start with a 6.5" x 12' utility trailer (red), and best blend Bezier curves in 3D. 
The roof angle(s) are likely too steep though...and the axle length(of a stock trailer) will cause need for wheel fairings outside of the envelope.
... but the length would be more manageable, and more space usable. |
The 'exposed' wheels are a 16% drag increase according to Elliott G. Reid at Stanford University.
The air would never follow that roofline I'm afraid. I'd have to do a comparison to establish where the boundary layer would separate.
The 22-degree 'limit' has been used by the Douglas Aircraft Corp., French navy, Swedish navy, US Navy, Dusky Dolphin, Atlantic Spotted Dolphin, Porbeagle Shark, Clark-Y airfoil just before burble-point, PGA and WPGA golf balls.
Kamm never went beyond 21.5-degrees.R.G.S. White used 20.5-degrees. The USEPA recommended 22-degrees.Volkswagen's lowest drag 'Flow-Body' was 21.5-degrees. NASA, 20-degrees, Daihatsu UFE-III, 13.5-degrees, Volkswagen XL1, 17-degrees, Mercedes-Benz IAA, 21-degrees, CYBERTRUCK, approx. 21.5-degrees, Mercedes-Benz EQXX, 13-degrees in plan-view, Buchheim, Piatek, and Walzer' curved-roof sedan, 21.5-degrees, GM Aero 2002, 21-degrees, LOREMO, 19-degrees, LIGHTYEAR ONE, 21-degrees.
