We owned an Airstream in the late 60's/early 70's. It was the "best towing" RV we've ever owned. But, with that "silver tube" aerodynamics comes "curved upper cabinet walls, lack of headroom at the sides of the trailer and a "head clunker" at both ends of the trailer.
We regularly towed it across Kansas on I-70 and never had issues with crosswinds. Essentially, it was a "one hand on the wheel" experience. The first trip with our Jayco (much shorter but "flat walls") had us "wishing for the Airstream" as we were blown from lane to lane by the gusts!!!
As for "fuel consumption", it takes energy to pull 10K trailers across the country. The shape of the trailer does have "some impact" on the fuel economy, but depending on the size of the tow vehicle in front of it and the weight, for most applications, there isn't much difference in fuel use. "Back when" we averaged about 9 with the Airstream and our Dodge 3/4 ton, and about 9 with our Jayco. The biggest difference was the length and weight between the two. That "sort of" equaled out the fuel use. I suppose with a Jayco as long and heavy as the Airstream, we'd have seen a fuel increase, but for us, it was about the same mileage with both units.
