You’ve worked hard and smart all of your life dreaming of the time when all your efforts could be realized in something like this state-of-the-art 2020 Newmar Mountain Aire 4543.  The grandeur of this Newmar luxury motorhome will only be exceeded by the magnificent vistas you’ll encounter like Monument Valley and the Grand Tetons.  The Spartan K3 chassis with passive steer tag axle technology will be the backbone of this customized Mountain Aire RV with over 23 optional upgrades including some King Aire influences.  The Cummins X12 500 HP diesel engine will have you scaling the Rockies, Smokies and Sierra Nevada mountain ranges with ease.  The Allison 4000MH six-speed automatic transmission glides smoothly from sea level at the Everglades to the mountain tops of the Appalachians. 

Driver Technological Features for Smooth Sailing
Two of the fantastic driver-friendly features found on the 2020 Mountain Aire include the industry envious Comfort Drive Steering System, and the On Guard Collision Mitigation Adaptive Cruise System.  The former auto-centers the coach after 90-degree turns and has a wind resistance compensation feature when driving the open highways.  The On Guard System monitors your traveling distance to the vehicle ahead – providing warnings and auto-braking should a safe following zone be compromised.

Elegance Inside and Out
The Barnsley Full-Masterpiece Finish is complemented by stainless-steel trim on the baggage doors giving this eye-catching luxury motorhome even more bling!  The interior features an upgrade to the King Aire solid surfaces and heated sub-floor with plank-like tiles.  The Windsor decor is tastefully understated, but rich in texture and feel.  The padded tile ceiling makes the Mountain Aire even more quiet inside the coach.  The warm Carmel Glazed Cherry hardwood cabinetry enhances the Mountain Aire experience.  A pair of swivel recliners separated by a convenient lampstand are positioned opposite a Dormi sofa/sleeper with a large 50-inch Samsung flatscreen LED TV on a power lifting Televator.

Culinary Kitchen Delights
The well-appointed galley on this new Mountain Aire features a Whirlpool residential-size refrigerator with water, icemaker and a freezer drawer.  This all electric RV offers a dual-burner True Induction portable cooktop for in motorhome/or campground picnic table cooking flexibility.  A microwave/convection oven handles campground party appetizers or simple leftover reheating.  Meals are served at the Euro booth dinette with two additional folding chairs to welcome RV resort guests.  Clean-up is simple with the dual stainless-steel sinks and the dishwasher in a drawer.
