2021 Airstream Interstate Grand Tour
The Airstream Interstate line has earned the title of America’s #1 best-selling Class B diesel motorhome for six consecutive years. Why? Because it blends Mercedes-Benz’s legendary safety and performance with Airstream’s unmatched craftsmanship and luxury.
With three available floor plans—Interstate 19, Lounge, and Grand Tour—this blog focuses on the 2021 Interstate Grand Tour, designed for travelers who want to take their home on the road without sacrificing comfort or performance.
? Chassis & Performance
Built on the Mercedes-Benz Sprinter VS30 chassis, the Grand Tour offers over 50 best-in-class features standard. From rear- and side-view cameras to driver-assist tech, the Interstate ensures a safe and smooth ride.
Powered by a 3.0L V6 Turbo Diesel engine, owners can expect fuel efficiency averaging 18+ MPG on the highway. Its compact footprint (24′6″ long, under 10′ tall) means you can access places that many larger RVs cannot.
