The 2024 Mountain Aire is your next step up in luxury travel. Inside, you’ll find finer amenities, options, and features to help you refine the coach to your own lifestyle—and start enjoying your road trips in comfort and style.

The 2024 Mountain Aire is available exclusively on a Spartan® K3 Tag Axle chassis, with 525 horsepower and 1,695 lb./ft. of torque. It’s available in five floor plans, ranging from 38 to 45 feet in length.

The 2024 Mountain Aire luxury motorcoach is available in five floor plans, ranging from 38 to 45 feet in length. There are two new floor plans, both 38 feet long: 3823 is a quad slide, rear-bed, mid-bath model; and 3825 is a full wall slide model with a bath and a half.

The 2024 Mountain Aire is available in four color options for the full-paint Masterpiece Finish™, an industry-exclusive graphics treatment that is carefully applied in-house and includes a cut and buff clear coat finish resulting in a mirror-like shine. There are also four interiors to choose from and four wood cabinetry stains.

The 2024 Mountain Aire isn’t just luxurious for comfort’s sake. It looks good too. From the cockpit to the living space, the galley to the spacious bedroom, the Mountain Aire comes with gorgeous décor and stylish furniture—sure to fulfill your desires.

Amenities are a core component of our luxury coaches, and the Mountain Aire has them in spades. From Apple CarPlay® on the standard 10” dual-monitor Xite Dash Radio, to the standard Samsung® LED TVs, to something simple like pullout shelves in the pantry, the little things make a big difference.

The 2024 Mountain Aire is supported by our STAR Foundation, which improves strength and durability while providing a quieter and more stable ride than any other Class A coach. A Spartan® K3 Tag Axle chassis, 525-horsepower Cummins® diesel engine and Comfort Drive™ adaptive steering with Passive Steer technology come standard. 

What’s more, each Mountain Aire is fitted with a cargo liner, 5/8” floor decking, 5/8” bead foam, and galvanized sheeting to prevent distortion. Lengths, heights, widths, and dry weights are approximate. Weight will vary based on optional equipment added to the base weights listed below. Specifications are supplied by each chassis manufacturer.
