2026 Airstream Interstate 19GTX Advanced Power, The 2026 Airstream Interstate 19GTX combines the refinement of Airstream s luxury Interstate line with the capability to take your travels well beyond the pavement.

 

Built on the Mercedes Benz Sprinter 2500 AWD chassis, the 19GTX is powered by a 2.0L High Output Turbo Diesel producing 208 horsepower and 332 lb ft of torque. FOX performance suspension, all terrain capability and its compact footprint make it equally comfortable navigating mountain roads, desert campsites or the city.

Inside, the GTX is unmistakably Airstream. Premium finishes, a full galley, wet bath and power rear lounge create a comfortable living space that converts into a 66" x 72" bed. It seats up to four while traveling and sleeps two.

 

This coach is equipped with Advanced Power Plus, expanding the lithium battery system to an impressive 17.2 kWh. Combined with a 3,000 watt inverter, 240 watts of rooftop solar and a powerful secondary alternator, Advanced Power Plus gives you substantially more freedom to run the air conditioner, appliances and outlets away from shore power. The all electric coach eliminates the need for propane, with heating and hot water utilizing the vehicle's diesel fuel when needed.

 

Additional highlights include Mercedes Benz AWD, FOX performance suspension, 5,000 lb maximum towing capacity, 24.5 gallon diesel fuel tank, 20 gallon fresh water tank, 13,500 BTU air conditioning, induction cooking, macerator waste system and Mercedes Benz MBUX technology.

 

The Interstate 19GTX is built for the traveler who wants to get farther off the beaten path without giving up the comfort, technology and luxury of an Airstream.
