This new Interstate is exactly what I've been waiting for. Very Happy that Airstream decided to incorporate the newest technology. It is this that differentiates it from all other B conversions and especially the Winnebago and Navion chassis conversions. While I like the Navion IQ, it simply can't keep up with these new features (doubt you can even get that chassis with the safety package from MB).
I have a 2014 E-250 and the updated interior has many similarities to my Benz (particularly the steering wheel which is very ergonomic... especially the little thumb notches.. you have to try it out to know what I am talking about.) Glad they stuck with the 3.0 diesel. I have the 2.1 4 banger in my car and it is great, and I regularly top 45 MPG, but have doubts it could power the Van very well. Besides, I want the reserve power for towing. I also have all of the bells and whistles and "Nanny" features on my car except for the "active" features (I prefer to keep control of the steering and brakes myself, thank-you), so this Van corresponds very well to my preferences.
Looking forward to test driving one! May be selling or trading in my 23ft Safari SE LS for one of these.
