Depends what Ed wants to make- an aero pull-behind that also hauls cargo, or a trailer that is also aerodynamic. Yours, Frank, is the former, and mine is the latter. Two different ways to approach the same problem.
I don't know how big the gap would need to be to really hurt the mileage but it'll probably be a meter or so from the get-go.
