50+ Best-in-Class Features Come Standard
We’ve always been focused on quality, standout design, and attention to detail. And in the Interstate Lounge, 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® 3500 Sprinter van chassis and add more than 50 best-in-class features as standard, not upgrades. And 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.
Entertainment In Style
The Lounge is designed with everything you need to entertain in style. Prepare and serve snacks and drinks on the galley’s Corian® countertops. Store your entertaining accessories in the European-style curved cabinetry, made from gorgeous matte veneers. And relax on the plush, sumptuous Ultraleather® seating surfaces. The Lounge is ready to impress at every turn.
