The url=http://www.airstream.com/trailers/2003/safari/specifications.html]specs[/url]appear to be filled in now. They call it a 28, but it's 29'. At dry weight, it's over 1100 lbs heavier than an '02 27 (27'11") Safari. In fact, it's almost within 100 lbs of the 28 (29') Classic and has the same 54 gallon fresh water, vs the 27' Safari's 39 gal. Also looks like you're giving up more than half the wardrobe space of the 27 Safari or 28 Classic, and a lot of the pantry space, but you pick up space in the dinette seat bases.
Just some observations...
