Rugged capability meets first-class touring comfort in the New 2026 Airstream Interstate 19GTX, a premium Class B motorhome built for travelers who want adventure-ready styling without giving up Airstream luxury. Measuring just 19 feet 5 inches long, the 19GTX rides on the Mercedes-Benz® Sprinter 2500 Extended AWD chassis and is powered by a 2.0L high-output turbo-diesel four-cylinder engine producing 208 horsepower and 332 lb-ft of torque, paired with a 9G-TRONIC Plus automatic transmission. With a 9,050-pound GVWR, 13,930-pound GCWR, and towing capacity up to 5,000 pounds, this compact touring coach combines impressive maneuverability with confident all-wheel-drive performance.

Inside, the Interstate 19GTX retains the refined living space of the 19GT while adding a tougher exterior personality. Premium seating accommodates up to four passengers, while the power rear sofa and ottomans convert into a generous 66"" x 72"" sleeping area for two. The galley includes a 3.2 cu. ft. 12V refrigerator/freezer, 1,000-watt induction cooktop, 0.7 cu. ft. microwave, solid-surface countertop, sink, and slide-out work surface. A space-saving wet bath adds a shower, toilet, sink, articulated mirror, and retractable clothesline, while dual 24-inch smart TVs, premium cabinetry, power shades, and signature aluminum trim create the upscale atmosphere expected from an Airstream touring coach.

The 2026 Airstream Interstate 19GTX separates itself with an adventure-ready exterior featuring a Tenzing front brush guard with integrated LED lighting, durable lower-body protection, black aluminum wheels, rugged all-terrain tires, black running boards, and FOX 2.5-inch Performance Elite Series shocks and struts. Its advanced electrical system provides 10.3 kWh of heated lithium battery capacity and a 3,000-watt pure sine wave inverter, while a 13,500 BTU soft-start A/C, Truma Combi Eco Plus heating and hot water system, heated fresh and gray tanks, and 20-gallon fresh water capacity support comfortable adventures beyond traditional campgrounds.
