The Interstate Grand Tour EXT is a Class B RV that elevates your travel experience when you’re setting out on a long-term journey for two. The very first time you step inside the Grand Tour you’ll find we’ve thought of everything to make your trips more enjoyable – from cooking to freshening up to getting some rest. And it’s that kind of thought that’s made the Interstate line the #1 best-selling Class B diesel motorhome for the past six years. Explore more of the Grand Tour, and then get ready to explore the world around you in complete comfort.

50+ best-in-class features come standard
We’ve always been focused on quality, standout design, and attention to detail. And in the Grand Tour, the result of our passions is one of the finest Class B RVs on the road. We start with the foundation of a Mercedes-Benz® Sprinter 2500 van chassis and add more than 50 best-in-class features as standard, not upgrades. That means the very best in safety, performance, interior design, comfort, efficiency, and more are all on board each and every time you hit the road.
Mercedes-Benz driving experience
Our partnership with Mercedes-Benz just comes naturally. Mercedes-Benz’s reputation for the best safety and convenience matches Airstream’s standards for lasting quality. That’s why we include more Mercedes-Benz safety and performance features than anyone else, from rear- and side-view cameras and assist features to the Parktronic parking system. We also add in features of our own, like Air Ride Suspension for a smooth ride in virtually any road conditions.
Kitchen, Bathroom, and Sleeping Space
Traveling in your Grand Tour means you won’t leave any comforts of home behind. The well-appointed galley kitchen boasts Corian® countertops, in addition to high-quality cabinetry handcrafted from fine woods imported from Italy. The luxurious sleeping quarters ensure a peaceful night’s rest – or a refreshing afternoon nap. And the bathroom is full of clever features that work hard and stay neat and clean.
