Airsteam use rubber toggles on the fornt window cover so they would have to be looked at carefully given your experience.
Thanks for sharing!

You may be right. It might not give much of a bump in fuel economy as you already have a pretty aerodynamic trailer. You can tell from looking at my rig, that it was not made to be low drag.
On the Airstream, I would think you could gain a little bit by considering some improvements on the awning arms (rounded fronts) and faring the a/c, if possible. You may gain much more by reducing air flow under the truck. As I mentioned, I think a bigger air dam on the Excursion would help.
