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.
