You're going to love the amount of space you have in this coach thanks to the full-wall slide and two additional slides! Wake up each morning feeling refreshed after sleeping on the king bed slide out, then grab your clothes from the bedroom dresser and head to the rear bath to clean up. Here, you'll find a 50"" x 34"" shower with a seat, a wardrobe with sliding doors, a large sink with two faucets, plus a Samsung two-piece stacked washer and 220 volt dryer. The tri-fold sofa and comfort lounge in the main living area provides more sleeping space if you need it, and the Euro booth dinette will be the perfect place to dine at in the morning. The kitchen comes standard with a stainless steel Viking convection microwave and 19.8 cu. ft. refrigerator with a 36"" French door and internal ice maker, plus an all-electric cooktop with a Wolf induction for hassle-free cooking. 

 

Luxury abounds in the King Aire Class A diesel motorhomes by Newmar. Each coach sits on a durable Spartan k3 tag axle chassis with the exclusive STAR foundation for added strength, durability, and better handling. You will love the Italian leather captain's seats, along with the industry-first Comfort Drive adaptive steering, Xite dash radio, wireless charging mats, and many more features to make the drive that much smoother. There are auto motion power shades inside, along with tile flooring, a down alternative fitted bedspread, and European style hardwood cabinets to name a few luxuries. The outstanding beauty doesn't end there; there are also super polished quartz countertops, full tiled shower walls and floor, electric radiant heat below the main floor tile, and the list goes on! Some of the innovative electrical features include a lithium ion battery system, a 12.5 kW Cummins Onan diesel generator, a doorbell and camera system, and a passive entry system. Each model can also be customized to your liking with traditional or contemporary exterior design options, four interior decor choices, and four hardwood stain options available in diamond gloss and suede finishes!
