Incredible Features

The experience inside the King Aire has been elevated from the cockpit to the rear bedroom. Starting with two heated and cooled full-leather captain’s chairs with a standard massage feature, the dash has been redesigned completely and is also covered in leather. The standard navigation system displays on the driver’s side screen, as well as on the passenger side monitor. A Harman Infinity® audio system will delight your inner audiophile with crystal clear sound. A Samsung® touch screen tablet allows you to adjust lights and shades, and control electronics with a single swipe. Of course, Internet connectivity solutions come standard, as do wireless charging pads.

The living room is designed for the lap of luxury. Two large bonded windows give an uninterrupted view of the scenery. Furniture is made from the finest Italian full grain leather, including floor plan-specific options for a Power Comfort Lounge Sofa and Visionary Trifold Sleeper Sofa. Accent-lit theater seating is also an option, with standard heat and massage. In the kitchen, you’ll find all-new hardwood European-style cabinetry with a diamond gloss finish. The appliance suite features top-tier residential equipment, like a Viking® stainless steel refrigerator and convection microwave—which is hidden behind a power-operated hardwood cabinet door. A Wolf® induction cooktop, Fisher & Paykel dishwasher, and a Hansgrohe faucet round out the design. A new marble backsplash and accent lighting make the space feel even more luxurious.

The 2021 King Aire is fitted with a cargo liner, 3/8” floor decking, 1 1/4” bead foam, and galvanized sheeting to prevent distortion. Each King Aire is supported by our ultra-durable STAR Foundation for a quieter ride. A 605-horsepower Cummins® X15 diesel engine with Connected Diagnostics™ and Comfort Drive™ adapted steering come standard.
