The Interstate is Airstream's long-running Mercedes-Benz Sprinter touring coach and the most established Class B in the brand's lineup. Built on the Sprinter 3500 platform with the Mercedes turbo-diesel, it pairs car-like drivability and Sprinter active-safety tech with Airstream's premium interior fit and finish in a van that parks in a standard spot. The 2026 lineup is broad — 19- and 24-foot bodies in GT, GL, GLX, GTX, and X trims, plus an off-grid-leaning 19X — sleeping two, with layouts spanning lounge, twin, and pass-through configurations. Standard equipment leans premium: a refined galley, a wet bath on most plans, and the Mercedes drivetrain's safety and efficiency. On RV Insider the Interstate sits at about 4.0 stars over roughly 39 reviews — solid but below the towable trailers — and some recent-unit owners cite electrical, lithium-system, and dealer-support issues alongside praise for the driving experience and off-grid capability. The honest trade-offs are price and complexity: the Interstate runs from roughly $240,000 to $293,000, a steep premium for a two-person van, and the diesel Sprinter drivetrain needs specialized service. For buyers who want a premium, drivable diesel touring coach with the Airstream badge, it is the brand's benchmark van.
