Powered by the dependable Mercedes-Benz 3.0L V6 Turbo Diesel engine producing 188 horsepower and 325 lb-ft of torque, paired with a smooth automatic transmission and desirable 4WD capability, this coach delivers confident all-weather handling, exceptional highway comfort, and fuel economy estimated at over 18 MPG. The extended 170-inch wheelbase provides excellent stability while still remaining compact enough to fit in many standard parking spaces, making it ideal for cross-country touring, weekend adventures, tailgating, or luxury camping.

Inside, the Grand Tour floorplan offers one of the most refined and spacious interiors available in a luxury touring coach. Premium Ultraleather seating, handcrafted cabinetry, Corian countertops, ambient LED lighting, and upscale finishes create a sophisticated atmosphere throughout the cabin.
