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.

NEW 2026 Airstream Interstate 24GT Class B Diesel Motorhome – Premium Adventure Van with Luxury Comfort
Airstream Interstate 24GT highlights:
Mercedes-Benz Sprinter 3500 AWD with 2.0L High-Output Turbo Diesel
Power Rear Sofa that converts into a 70" x 82" bed
10.3 kWh Lithium Battery System with built-in heater
400W Solar Power System
Large Rear Lounge with flexible seating and dining configurations
14' 6" Power Armless Awning with auto-retract and LED lighting
The new 2026 Airstream Interstate 24GT brings together the performance of a Mercedes-Benz Sprinter with the refined design and premium craftsmanship Airstream is known for. At 24' 6" long, this all-wheel-drive touring coach offers an impressive combination of maneuverability and livability. Its Mercedes-Benz Sprinter 3500 Extended chassis, 2.0L high-output turbocharged diesel engine, and 9G-TRONIC Plus automatic transmission produce 208 horsepower and 332 lb-ft of torque, while the available tow package allows for towing up to 5,000 pounds.
The 24GT's rear lounge is the centerpiece of the coach, giving you a versatile space that can change throughout the day. The standard power rear sofa provides comfortable Ultraleather seating during the day and transforms into a generous 70" x 82" sleeping area at night. Two Lagun modular tables can be positioned in multiple locations inside or outside, making the space useful for dining, relaxing, working remotely, or entertaining. Two 24" widescreen Smart HDTVs and premium speakers provide entertainment wherever the day takes you.
The galley is compact but thoughtfully equipped for preparing meals on the road. Standard equipment includes a single-burner induction cooktop, 1.2-cu.-ft. drawer microwave, 6.6-cu.-ft. 12V refrigerator with freezer, solid-surface countertop with aluminum backsplash, and stainless-steel sink with cover. A pantry with built-in drawers and shelves provides additional storage, while the built-in workstation behind the driver's seat creates a convenient place to handle emails, plan the next destination, or get some work done while traveling.

The space-saving wet bath includes a foot-flush toilet, removable handheld showerhead, sink with articulated mirror, integrated LED shower lighting, towel rack, retractable clothesline, and exhaust fan. Throughout the cabin, the 24GT features signature aluminum ceiling and trim, matte laminate cabinetry, flush-mount cabinets with positive-locking hardware, power day/night shades, marine-woven synthetic flooring, adjustable LED lighting, overhead storage, under-bed storage, and Ultraleather seating. The result is a sophisticated interior that feels purpose-built for comfortable touring rather than simply being a van with a few RV amenities added.
Power and off-grid capability are another major strength. The 24GT comes standard with a 10.3 kWh deep-cycle lithium battery system with built-in heater, 400W total solar power, a 130-amp multi-stage charger, 3,000W pure-sine Xantrex inverter, and 30-amp shore power. Heated fresh and gray tanks, diesel-fired hydronic heating and hot water, and a 13,500-BTU A/C with soft start provide four-season-style comfort while traveling. The coach carries 23 gallons of fresh water, 24 gallons of gray water, and 11 gallons of waste water.
On the road, the Interstate 24GT adds an impressive collection of standard Mercedes-Benz safety and driver-assistance technology, including Active Brake Assist, Active Lane Keeping Assist, Active Blind Spot Assist, Active Distance Assist, Active Driver Attention Assist, Active Rear Cross Traffic Assist, Traffic Sign Assist, Front and Rear Parktronic Parking Assist, and rear camera assistance. Outside, the coach features a power armless awning with auto-retract, power entry step, exterior shower, LED patio and undercarriage lighting, locking service boxes, power heated mirrors, fog lamps, and a hidden hitch-cover rear bumper.
