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.
