Incredible Features
The captain’s and passenger’s seats in the Mountain Aire are made for comfortable travel. Both heated and upholstered in Ultraleather®, they’re also both appointed with amenities. The captain’s chair features dual 10” monitors equipped with Rand McNally navigation, with an option for a passenger side navigation monitor as well. Haptic feedback has been added to help the driver stay aware of surroundings–and that’s in addition to the 360-degree camera system with predictive grid lines and tri-view rear camera. The passenger gets a queen-size seat with a workstation and footrest.
The galley of the 2021 Mountain Aire serves up the classic appointments of home with the beauty of a Newmar. Appliances include a Whirlpool® refrigerator, a 30” convection microwave, and a two-burner cooktop. Add an optional dishwasher, or a kitchen window to allow more light to stream in. In the master suite, you’ll find a dresser with six large drawers and super-polished countertops and two wardrobes. For late-night entertainment, there’s a Samsung® LED TV and Sony® Blu-ray player—plus, you’ll find a touch screen control panel to oversee many of the coach’s functionalities. A king-size bed comes with a plush pillow top mattress, or you can upgrade to a Sleep Number® adjustable mattress.
The 2021 Mountain Aire is fitted with a cargo liner, 5/8” floor decking, 5/8” bead foam, and galvanized sheeting to prevent distortion.
