2019 Airstream Interstate 19, ==== Largest bed in its class ====With a power sofa and side seats that convert into a sleeping space, you get the best of both worlds in the Interstate Nineteen. Relax or catch up on emails on the sofa during the day, then push a button and the sofa becomes completely flat. The side seats hinge and lie flat as well, so the entire rear of the coach becomes a comfortable bed -- and at 66" x 73" it's the largest bed you'll find in a Class B RV.==== C-Zone Multiplex Controls for shades, lighting, and more ====You can open or close all of the shades in the Nineteen with one touch on the C-Zone control screen. The same goes for the interior lighting, the power awning outside, and features like the air conditioning, generator power, and more. You can also monitor tank and power levels with easy digital readouts on the C-Zone screen.==== Spacious, versatile bathroom ====The European-style wet bath in the Interstate Nineteen neatly houses a sink, shower, and toilet, plus a built-in shampoo, conditioner, and body wash station and a clothesline -- everything you need to feel clean and energized on the road. Every inch of the space is designed to get wet, and every function is smart and efficient. The showerhead doubles as the faucet, the mirror extends and swivels, and there's a totally waterproof toilet paper cover.==== Mercedes-Benz(R) performance and safety ====The powerful Mercedes-Benz 3.0L V6 turbo diesel engine makes the Nineteen driving experience so enjoyable -- with powerful getup balanced with impressive fuel economy. And standard-setting Mercedes-Benz safety features are everywhere you look in the Nineteen, including lane keeping assist, collision prevention assist, rear- and side-view cameras, the most airbags available from Mercedes-Benz, and a FUSION(R) Infotainment System with Garmin navigation and lane guidance.==== Airstream Air Ride Suspension ====The rear of the Nineteen is equipped with our exclusive optional Air Ride Suspension which adjusts itself to bumps in the road, changes in elevation, and changes in wind resistance, so you can enjoy a smooth ride, mile after mile.
