2026 Airstream Interstate 19GT

Interstate 19GT gets you as close to the action as possible.
Featuring Airstream’s powerful new standard Advanced Power System and outfitted with luxurious design choices throughout

Designed for efficient, easy travel—to the city, the beach, the mountains, or beyond—without sacrificing luxury or amenities, Interstate 19GT has it all. At only 19 feet long, it’s as easy to park as an SUV, but with a full suite of luxurious features for comfortable travel and living. Want to be as close to your next adventure, event, or everyday outing as possible? The Interstate 19GT will fit right in. Want all your at-home comforts, like cooking meals, storing cold beverages, and kicking back in the A/C? That’s what Interstate 19GT was designed for. With 10.3 kWh of lithium power, Airstream’s new Advanced Power System fuels your appliances, outlets, induction cooktop, and more, so you can enjoy off-grid living without sacrificing everyday pleasures.

For someone whose life moves as quickly as a well-hit pickleball and zigs and zags like a world class opponent, it’s a relief to count on the Interstate 19GT’s ease of use and powered features. Close the blinds, open the awning, dim the lights and more at the touch of the button with Interstate 19GT’s touchscreen multiplex control panel. And with the standard Advanced Power System, comfort can be found anywhere you choose to park or camp–whether it's a National Park, the golf course, or the pickleball complex.

The Advanced Power System

In 2026, Airstream introduced the standard Advanced Power System to its luxurious lineup of Interstate and Atlas Touring Coaches. A massive battery system, powerful solar capacity, and an off-grid ready inverter mean no matter where you travel, you’re taking comfort along for the ride. For even more off-grid power potential, Interstate 19GT can be upgraded with the optional dealer-installed Advanced Power Plus system. 

Setting the New Standard for Off-Grid Power and Capability

Engineered for effortless energy management, the Advanced Power System delivers more power, simplifies off-grid travel, and takes Airstream innovation to the next level.  

From fully electric appliances to low-speed charging and expanded battery capacity, the Advanced Power System is a complete solution for modern travelers who expect their coach to keep up with the way they live and explore.

• 10.3 kilowatt-hours (kWh) of usable battery capacity, capable of powering the A/C for 8 to 10 hours without relying on shore power or generators  

• A single-fuel energy system powered by the diesel fuel already in the vehicle’s tank  

• An all-in-one heating and hot water system that delivers consistent interior warmth and on-demand hot water 

• Low Speed Charging with an alternator that delivers up to 3,000 watts of charging power at low or no speed 

• Up to 400 Watts of solar charging capacity (depending on the model) with external solar ports for additional portable panel integration  

Single-Fuel-Source Efficiency

Whether boondocking in the backcountry or darting off to the next pickleball tournament, Interstate 19GT’s efficiency will keep you going, even when you have lots of time away from shore power. From the refrigerator and microwave to the water heater, furnace, and induction cooktop in the galley, the appliances in Interstate 19GT are all powered by electricity. The van’s powerful inverter and huge lithium battery bank allow owners to operate all functions even when far from shore power. Like the innovative Airstream Trade Wind^® Travel Trailer that preceded it, the Interstate 19GT easily runs appliances while backcountry camping or going off-grid on a pristine beach. (Appliance run times will vary depending on variables like local weather conditions and owner operation.)   

Comfort and Functionality at the Heart of Interstate 19GT

No matter if you’re a professional athlete or a part-time adventure-seeker, rest is crucial. For those who value rest as much as action, Interstate 19GT has the largest bed in its class. The power sofa and side seats convert into a sleeping space, so you get the best of both worlds. Relax or catch up on emails on the sofa during the day, then push a button and the sofa becomes completely flat. The side seats hinge and lie flat as well, so the entire rear of the coach becomes a comfortable bed – and at 66” x 73” it’s the largest bed you’ll find in a Class B RV.
