I stopped by the Hall of Fame today of course expecting to see an Airstream too (Wally was in the first class inducted though). I asked the desk volunteer about this obvious oversight and received an ear full! He said that before they moved to the new building (which is amazing) they had a vintage Airstream TT from the factory but it was sent home during the collection transfer and was never returned. They have asked continuously for one since with no result. Curiously he did say something about a '74 Bambi being offered and refused because it was too new
All that aside the visit was well worth it even though the site is barely half completed. They hope to complete a conference center and motorhome display area soon. They do have a few interesting areas open to the public: the vintage trailer gallery, an extensive library, and an area set aside to show current offerings from a variety of manufacturers. There I loved the off-road, toy-hauling tent-camper
My wife was impressed by the big plush motorhomes but to her credit her favorite was a '64 coachmen Cadet. My favorite was the '57 Serro Scotty teardrop. The public is allowed to to self tour most of the travel trailers which puts them in great peril but none are too immaculate in the first place so I didn't feel too bad.
If you are travelling through northern indiana on the toll road it's just a 2 minute drive from the Elkhart East exit.
