trentlyle, I will not claim to be a Touareg expert but can offer real world experience. Our first Airstream was a 2018 Flying Cloud 23FB. We towed it with a 2016 Touareg TDI and Blue Ox SwayPro WD hitch.
The Touareg is a very capable tow vehicle with 6 piston caliper brakes and short rear overhang. The factory hitch was rated at 770 lbs. max tongue weight and the vehicle’s payload was 1168 lbs. I added a Prodigy P2 brake controller connected to the factory harness under the dash. eTrailer has a video on how to install it if you’re interested. There are some wireless controllers out there now too.
The combination was very stable and we averaged 16 MPG towing. Have you checked out the Touareg, Audi and Porsche thread? Lots of great information there.
Good luck with your new rig and happy camping!
