I am also on the Airstream forum and like any forum you have to weigh all the comments. They seem to think that since you have an Airstream you need to jump in and spend 2 to 3K on a hitch. If you had a really big trailer, maybe that is the way to go.
I tow my 25 with an Equalizer and really like how it works. It is easy to connect and disconnect, you can back it up and I have never had a white knuckle experience in over 40K miles towing.
You are going to like your trailer. They tow really well. I had a Starcraft hybrid that was 5 feet shorter and about a ton lighter. The Airstream tows much better and I am getting just about the same mileage now.
