A little better than a sphere (≈0.47) maybe? Worse due to awnings, A/C, and other stuff?

I think we tried an estimate earlier. Search posts by
aerohead and Airstream.
The gap between tow vehicle and trailer is more to the point. And, that crosswinds do not pile up and push against the trailer so much as that they flow over the radiused edges and exert a "pull". Much easier to live with and definitely has less of an affect at the steering wheel.
THe Airstream supplied figure is that it takes 20% less fuel to pull one.
HI-LO is another brand to look at.
