New member getting ready to buy.

I am a new member looking forward to crossing the country in my new or vintage Airstream next summer. I like the layout and specifications of the International 27FB and recently enjoyed taking the factory tour. My only concern is that I have heard that Airstreams can be like ovens in hot sunny climates, including the newer models with EcoBatt insulation. The industry wide solution appears to be to use a lot of air conditioning, four to five times as much as needed to cool an equal size room in a home. I am wondering if anyone has come up with a better "space-age" solution -- besides moving with the weather so its always 72 degrees outside. Input from electrical or mechanical engineers is welcome.



Thanks,

John
