The 4WD system is the headline here. Airstream engineered the Interstate 19 X specifically for travelers who want to push past the pavement without giving up the comforts of a premium Class B. Built on a Mercedes-Benz Sprinter 4x4 chassis, it handles mountain passes and forest service roads that would turn back a conventional motorhome. Inside, you still get a full bath and Airstream's signature fit and finish, proving that off-road capability doesn't have to mean roughing it. At 19 feet, it's also genuinely manageable in tight campsites and urban settings. The kind of rig you can take everywhere and actually want to drive.
Other class b motorhomes floor plans (around 19 ft 5 in, near $200,000), similar in size and price to the Interstate 19 X 4WD.
