Stock #477083 -

2019 Newmar Mountain Aire, Maintained Without Compromise.

This 2019 Newmar Mountain Aire 4579 is an upper-tier luxury diesel motorcoach built on the Spartan K3 chassis and powered by a 500-horsepower Cummins diesel engine.

The Spartan K3 chassis features premium air-ride suspension with automatic leveling and adjustable ride height, delivering a stable, confident driving experience. Newmar's Comfort Drive steering system allows the driver to adjust steering effort for highway stability or low-speed maneuverability, making the coach easy to handle in tight spaces while remaining composed at speed.

The Mountain Aire's weight and chassis design minimize lane disturbance from passing traffic. Adaptive cruise control and collision mitigation systems are integrated, automatically managing speed in traffic conditions. Engine braking provides strong downhill control on steep grades, reducing brake wear. An engine block heater is installed for cold-weather operation, and routine service has been performed as part of regular maintenance.

The cockpit is equipped with a fully digital dash, navigation, satellite radio, and a comprehensive 360-degree camera system providing full surround visibility. Side cameras automatically activate with turn signals, and split-screen views allow continuous monitoring of a towed vehicle. Both driver and passenger seats are power-adjustable, heated, and equipped with lumbar support and leg extensions, and they rotate to integrate into the living area when parked.

This Mountain Aire is an all-electric coach with no propane systems. Electrical power is supported by eight house batteries, a 3,500-watt inverter, and a 12.5 kW Cummins generator. An automatic transfer switch prioritizes generator power when running, while shore power is managed through an automatic 50-amp power reel. A Bluetooth-enabled surge protection system monitors incoming power. All major systems -- including electrical, lighting, climate control, slides, awnings, and diagnostics -- are managed through Newmar's SilverLeaf control system, with full access from both the front cockpit and the bedroom.

Climate control is handled by three roof-mounted air conditioners with heat pumps, supplemented by the Oasis hydronic heating system, which provides both electric and diesel heating capability. Heating source selection can be managed manually or automatically, depending on available power.

Heated tile flooring extends throughout the coach, including the living area, bedroom, and bathroom, with independent zone control. Both bathroom roof vents are equipped with rain-sensing technology and automatically close when moisture is detected.

The interior reflects Newmar's premium construction standards, featuring Amish-built solid wood cabinetry with dovetail joints and hand-finished details. Cabinetry throughout the coach is notably deep and offers extensive, functional storage. All flooring, including the slide-outs, is tile, with no carpet present anywhere in the coach. Decorative ceiling woodwork with integrated drop-down vent covers conceals HVAC openings, creating a clean, refined interior.

The living area includes a queen sleeper sofa with a built-in powered air mattress, power seating, an automated TV lift, accent lighting, and multiple power and USB outlets throughout.

The kitchen is equipped with full-size residential appliances, including a household refrigerator that remains operational while driving. An additional refrigerator/freezer is located in the basement for expanded storage. A deep pantry with adjustable shelving allows flexible organization. A built-in triple water filtration system is installed, supplemented by a portable water softening system, and the refrigerator includes its own dedicated water filter.

A key advantage of this floorplan is that, with all slides retracted, usable centerline access remains through the coach. The bathroom, refrigerator, and kitchen can be accessed while traveling without deploying slides. The mid-coach half bath provides ample space and includes a macerator toilet and vacuum inlet. The rear bath features a sink-and-a-half layout, substantial cabinetry, and one of the largest showers available in a Class A motorcoach. Both toilets are macerator-style and are monitored through digital tank level displays visible locally and through the SilverLeaf system. The Aquamizer function recirculates water internally until hot, minimizing water waste during dry camping.

The master bedroom includes a king bed with under-bed storage, multiple lighting modes including courtesy floor lighting, and a third television with surround sound. Exterior security lighting can be activated from the bedroom. Solid wood doors fully separate the living area, bedroom, bathroom, and walk-in closet. The rear emergency exit is located in the master bath and also provides convenient access for loading luggage near the closet. The walk-in closet offers extensive hanging and shelf storage, built-in shoe racks, a Whirlpool washer and dryer, and a built-in safe with restored access and multiple keys included.

Basement storage is extensive and well-organized, featuring multiple power-sliding cargo trays, exterior power outlets, and clearly labeled service bays. Included equipment consists of a Blue Ox tow system and tire pressure monitoring on all wheels.

The air-ride system includes onboard air access ports at the front and rear for inflating tires or accessories. Fueling access is available from both sides of the coach. The roofline is fully enclosed, concealing rooftop equipment for a clean and streamlined profile.

Overall, this 2019 Newmar Mountain Aire 4579 stands out for its condition, equipment level, and readiness. It is a fully luxury motorcoach that has been maintained to a high standard and presents as an excellent example of a Mountain Aire for buyers seeking a premium coach that requires no immediate work and is ready for travel.
