New Airstream Globetrotter

While Airstreams are not for me for many of the reasons mentioned.
Longevity is there selling point.
There are many 25-40 year old Airstreams that are in very usable shape.
While my rig is holding up very well so far.
I'm not sure how well my 5 slide behemoth will endure 40 years.
I don't think any of our main stream models compare to Airstream in terms of longevity.
