Experience the pinnacle of early luxury diesel-pusher craftsmanship in this 2007 Newmar Mountain Aire 4523. At 45 feet long and riding on a heavy-duty Spartan K2 chassis with Independent Front Suspension and tag axle, this Mountain Aire delivers the confidence, stability, and commanding road presence expected from one of Newmars premier coaches.
Power comes from the highly regarded Cummins ISM 450 HP 10.8L turbo diesela powerful pre-DEF engine built to handle long highway grades and serious towing. A two-stage engine compression brake, ABS, heavy-duty hitch with up to 15,000 lbs. towing capacity, and Newmars renowned Comfort Drive steering make this coach remarkably capable for its size. HWH computerized 4-point hydraulic leveling provides effortless campsite setup.
Inside, four expansive power slide-outs transform the coach into an exceptionally spacious residential-style retreat. The interior features UltraLeather seating, premium hardwood cabinetry, solid-surface countertops, and tile flooring throughout the living areas. Two large sofas provide generous seating, with one converting to a hide-a-bed for additional sleeping accommodations.
The upscale galley features a 2-burner recessed cooktop, stainless convection microwave, 13.9 cu. ft. residential refrigerator/freezer, and dedicated pull-out pantry. The sophisticated split-bath design includes a private powder room, porcelain toilet, large vanity, and a spacious fiberglass tub/shower with glass enclosure. A washer/dryer adds convenient residential functionality.
The rear master suite offers a king-size bed, cedar-lined wardrobe storage with sliding glass doors, and a concealed television compartment.
For true off-grid capability and four-season comfort, this Mountain Aire is equipped with Hydro-Hot hydronic heating and continuous hot water, three 15,000-BTU central A/C heat-pump units, and a 10.0 kW Onan Quiet Series diesel generator on a power slide-out tray. Additional capacity includes 105 gallons of fresh water, 50-amp electrical service, and a high-capacity inverter.
