If youve been searching for an Airstream Interstate Grand Tour EXT, this is an opportunity to own an exceptionally low-mileage example without paying the $200,000+ price of a newer Interstate.
This 2018 Airstream Interstate Grand Tour EXT rides on the Mercedes-Benz Sprinter 3500 diesel platform and combines Airstreams iconic aluminum construction with the comfort and functionality of a luxury touring coach.
ONLY 36,000 MILES
Thats the story of this coach.
At only 36,000 miles, this Interstate has traveled remarkably little for a 2018. It gives you the opportunity to own an established Airstream/Mercedes platform with many years of travel ahead of it.
RECENT UPGRADES
400 watts of solar
NEW windshield
NEW tires
NEW premium awning with extended tie-down legs
These arent cosmetic upgradesthey are improvements that make the coach more enjoyable and practical to own and travel in.
THE GRAND TOUR EXT
The Grand Tour is one of Airstreams most desirable Interstate floorplans, designed around comfortable travel, entertaining and extended stays.
Inside, youll find the distinctive Airstream environment that makes the Interstate different from a typical converted Sprinter van.
Its a true luxury touring coachcompact enough to drive and park comfortably, while giving you the ability to travel, sleep, relax and live comfortably without towing a trailer.
WHY THE INTERSTATE?
The Mercedes-Benz Sprinter 3500 diesel platform gives this coach the combination of:
* Mercedes-Benz diesel power
* Excellent highway touring capability
* 3500-series chassis
* Airstreams proven coach construction
* Luxury interior
* Compact Class B maneuverability
* The ability to travel without towing
* A configuration designed for both weekend trips and extended travel
And unlike many newer adventure vans that are built around a minimalist approach, the Interstate was designed from the beginning as a premium touring coach.
AIRSTREAM QUALITY
The Interstates aluminum construction, distinctive exterior and carefully designed interior have made the model one of the best-known luxury Class B touring coaches on the road.
This is not simply a Sprinter with a bed installed in the back.
Its an Airstream-built Mercedes-Benz touring coach designed for people who want the freedom of a motorhome without giving up comfort, quality or drivability.
