While Airstream’s Interstate and Interstate EXT Class B motorhomes have shuttled people back and forth in high-end style, customers who wanted a vehicle more capable of extended stays oftentimes were left behind. So, Airstream added the Grand Tour, which is essentially a new floorplan for the 24-foot, 4 1/2-inch long Interstate EXT built on the Mercedes-Benz Sprinter 3500 Series. “About 90% of our Interstates and EXTs were a nine-seat floorplan,” said Justin Humphreys, Airstream’s vice president of sales. “We found there is a new customer base that wanted to travel back and forth to their second homes in luxury. But if somebody wanted to go camping with them, the vans weren’t that comfortable. So we came up with the Grand Tour, which is more camper-friendly.” The Grand Tour removes the seating in favor of added storage, a larger refrigerator and freezer, an additional pantry and more hanging space for clothes. The Grand Tour also flips the galley from the driver’s side to the campsite side and adds a drawer microwave, bathroom/shower unit and a rear sofa (with storage behind it) that converts to a bed complete it.
