The Airstream Interstate 24GT earns its reputation as the best-selling Class B diesel motorhome by delivering a surprisingly complete living space on the Mercedes Sprinter 3500 platform, complete with air ride suspension and turbo diesel performance that makes long highway miles genuinely enjoyable. Inside, ultraleather seating, solid surface countertops, handcrafted cabinetry, and an induction cooktop set a standard most Class Bs don't approach. The high-capacity lithium battery system, diesel hydronic heating, and heated tanks give the Interstate 24GT real off-grid range, while a central touchscreen ties together power monitoring, lighting scenes, and climate control in one place. The one-piece wet bath with integrated LED shower lighting and a riveted aluminum porthole door are distinctly Airstream touches that remind you this isn't just a converted van.

Long-distance touring feels remarkably refined in the New 2026 Airstream Interstate 24GT, a luxury Class B motorhome designed around comfort, premium technology, and an exceptionally versatile rear lounge. Measuring 24 feet 6 inches, the 24GT rides on the Mercedes-Benz Sprinter 3500 Extended AWD chassis with a 2.0L high-output turbo-diesel engine producing 208 horsepower and 332 lb-ft of torque, paired with a 9G-TRONIC Plus automatic transmission. With an 11,030-pound GVWR, 15,250-pound GCWR, and towing capacity up to 5,000 pounds, it combines all-wheel-drive confidence with standard Air Ride suspension and sophisticated Mercedes-Benz driving technology.
Inside, the Interstate 24GT is designed to seat up to seven and sleep two, with a spacious rear lounge that transforms into a 70" x 82" sleeping area using the power sofa and ottomans. Ultraleather seating, power day/night shades, signature aluminum trim, premium cabinetry, dual 24-inch Smart TVs, and a built-in workstation behind the driver's seat create a comfortable environment for relaxing or working remotely. The large galley features a 6.6 cu. ft. 12V refrigerator/freezer, 1,000-watt induction cooktop, 1.2 cu. ft. drawer microwave, solid-surface countertop, stainless-steel sink, and pantry, while the space-saving wet bath provides an onboard shower, toilet, sink, and storage.
The 2026 Airstream Interstate 24GT is equally impressive when traveling beyond full-hookup campsites, with 10.3 kWh of heated lithium battery capacity, 400 watts of solar, and a 3,000-watt pure sine wave inverter. An available 17.2 kWh Advanced Power Plus upgrade provides even greater energy storage for extended off-grid stays. A 13,500 BTU soft-start air conditioner, diesel-fired hydronic heating and hot water, heated fresh and gray tanks, and 23-gallon fresh, 24-gallon gray, and 11-gallon waste capacities add four-season versatility. A 14'6" power awning, power rear screen, exterior shower, advanced energy-management controls, and available hydraulic leveling complete a touring coach built for luxurious extended adventures.
