RV Description

Beautiful and well-maintained 2014 Airstream Interstate Lounge EXT, built on the Mercedes-Benz Sprinter 3500 chassis with the 3.0L V6 turbo diesel engine. This luxury Class B touring coach combines the legendary Airstream build quality with significant upgrades that dramatically improve off-grid capability, ride comfort, and modern technology.

With only 44,800 miles, this coach has been well maintained and thoughtfully upgraded by a retired engineer with over $15,000 in improvements, making it far more capable and modern than most Interstate vans of this era.

The white exterior and black Ultraleather interior with light laminate cabinetry create a timeless and clean Airstream look. The rear power sofa converts into a comfortable sleeping area, while the (4) front captains chairs swivel to create a spacious lounge for relaxing or entertaining. Additional seating in the rear makes for a total of 9 passenger seating so that you can bring plenty of friends along for the ride.

This Interstate is road-trip ready and ideal for extended touring, off-grid camping, or luxury travel.
