Designed to impress

The Mountain Aire brings bold curb appeal with Newmar’s signature full-paint finish and the optional Onyx Package, which adds dark accents throughout. Dual power slide trays, a slide-out Dometic freezer with optional fridge upgrade, and lighted exterior storage make it both aesthetically pleasing and functional.
Pilot your ride

This coach is equipped with Newmar’s Comfort DriveⓇ steering system, providing a smooth and more controlled ride. The anti-glare digital dash displays vehicle information clearly, while a 360° stitched camera system improves visibility in tight turns and narrow spaces. Co-pilot controls feature a touchscreen display for clear navigation and camera views, making this setup ideal.
Room to relax

There’s tons of space to stretch out inside the Mountain Aire. The power theater seats feature hidden storage and illuminated cupholders, providing a cozy spot to kick back and relax. The Euro-style dinette features a hidden leaf extension and includes two folding chairs to seat extra guests comfortably.
A convenient kitchen

The Mountain Aire’s kitchen comes ready for meal prep, both inside and out. A portable dual-burner induction cooktop plugs in easily outdoors or on the counter, and a WhirlpoolⓇ convection microwave with built-in air fryer makes cooking easy. The single-basin sink is paired with solid-surface covers and cutting boards, and the dishwasher is tucked away.
Your bedroom retreat

In the back of the coach, the bedroom is spacious, bright, and is calling your name. A king-size bed with large nightstands features a built-in power station, while wardrobes with six full drawers provide ample storage. A SamsungⓇ Smart TV is positioned for easy viewing, and controls for lighting and shade are conveniently within arm’s reach.
Elevated bathrooms

This coach includes a spacious rear full bath and a convenient mid-ship half bath. In back, you’ll find a tiled shower with a rain-style head, built-in bench, extra headroom, and a water-saving system for off-grid travel. A stacked washer and dryer are also tucked into the rear. The half bath adds flexibility for guests.
