Home Away From Home

The Newmar Mountain Aire’s interior design feels more “home” than “mobile home.” Featuring hardwood cabinets with concealed hinges, ultra leather sofa, and super polished solid surface countertops in your choice of four color schemes, this coach is ready for your personal touches.
Show Stopping Exterior

The Mountain Aire’s exterior features Newmar’s exclusive Full-Paint Masterpiece Finish™ available in four striking color schemes. Newmar luxury coaches are fully painted, rather than using color wrappings. Framed 16 inches on center with a fiberglass roof and integrated gutter rail, you can be sure that your Mountain Aire is built on its SpartanⓇ K3 tag axle chassis from the highest-quality materials on the market.
Gourmet On the Way

Outfitted with a WhirlpoolⓇ 19.7 cubic foot refrigerator, convection microwave, and gas cooktop, you can whip up meals for your hungry travel companions in no time. And pullout pantry shelves, molded silverware divider tray, and designated storage for serving trays and bakeware in the pantry make entertaining on the road a cinch.
Storage Solutions

Newmar takes pride in offering the most discreet and ample storage on the market for travelers, and the Mountain Aire is no exception. There are full-sized wardrobes beside the lavatory, mesh cell phone holders next to each bunk bed, shoe storage shelves, and a redesigned bedroom dresser inside. The exterior boasts storage bins in the pegboard compartment, power baggage door locks, a 3.0 foot pull-out freezer, and additional storage trays in a variety of configurations.
Luxury Baths

A glass doored, tiled shower with a fold-down seat and in-shower soap dispenser make this lav feel like an upscale hotel bathroom. Fully-opening windows in the bathrooms allow air to flow throughout. For the more adventurous, there is also an exterior shower to enjoy the great outdoors.
Entertainment for Everyone

Passengers aboard the Newmar Mountain Aire can enjoy streaming on one of three SamsungⓇ LED televisions, supported by BoseⓇ subwoofer and sound bar in the living area. The dash radio is equipped with AppleⓇ Car Play and features a 10” dual monitor with Nav-N-Go Navigation, and the roof comes prepped for a satellite dish.
