I believe a 25' Safari is a good choice for many reasons. After looking at all of the AS models fom 16' to 28', we decided on the 25' Safari Front Bed, SE, LS Package, Audio/Video Package and Panoramic windows both front and rear. The LS package upgrades the AC from 11,000 to 13,500, which in my opinion does the job. We took a 9,000 mile tour of the US and traveled in a big loop which tooks us through all weather types. Nevada was the hotest, at 105 degrees, the AC cooled us down to mid 70s with no problem. The higher humidity states, like Florida, didnt get over 90 degrees when we were there, again, the AC worked great.
We have had only minor issues, all being taken care of by Airstream during a visit to the factory in Ohio. Overall, I would rate the AS quality as 8 1/2 out of 10, with the industry average being 3. Really, an 8 1/2 is good when you compare it to everybody else. But it just isnt the initial quality control that counts, its the lifetime quality that As is known for that can not be equaled, at almost any price by the competition.
Your tow vehicle (TV)is probably on the line for its capability, (sorry any other 1/2 Suburban owners, I mean no disrespect), a loaded 25' Safari weighs in around 7300 lbs, so look at your TVs towing capacity and go from there, that will tell you if it works in general. And yes, you will need a WD/Sway control, I use an Equalizer and a Prodigy brake controller and they work effortlessly. Everybody has their favorite hitch, the Equalizer is used by many AS owners.
