If you weren't nearly 3,000 miles away from Can Am RV, I'd suggest having them build a custom receiver. The image of the Audi unit makes me think they would have no trouble replicating the attachment points and augmenting the design to make it capable of handling a weight-distributing hitch.

I'd expect towing a good handling trailer like an Airstream with a good handling car like an Audi to be a rare treat. I wouldn't expect pulling power or cooling capacity to be issues. The gearing and torque are quite suitable, and these cars are designed to be run at wide open throttle or close to it. Using constant turbo boost may cause problems, but perhaps using a pyrometer to keep an eye on exhaust gas temperature would work as well for a turbocharged gasoline engine as it does for a turbocharged diesel.
