2021 Newmar Supreme Aire Super C Diesel Motorhome

2021 NEWMAR SUPREME AIRE

SUPER C DIESEL motor coach

At Home on the Range

A stunning new addition to our Super Class C lineup, the 2021 Supreme Aire provides a host of segment-first innovations, luxurious treatments, and thoughtful design elements. The Supreme Aire is an upgrade to the Newmar Super Star and is an instant classic in the Super C segment.

The 2021 Supreme Aire is even better suited to your travels—whether that’s a trip to the ranch or to a show near a city. It’s built on a Freightliner® M-2 112 chassis with a hefty 505 horsepower Detriot diesel engine, which also gives you a whopping 1,850 lb./ft. of torque–perfect for towing a trailer or spare vehicle. Saddle up and move 'em out in one of the Newmar Supreme Aire Super C motorhomes for sale at North Trail RV Center.

In the cockpit, we focused on comfort and convenience for your drive. Both air-ride captain’s chairs offer pneumatic lumbar support. A custom-tuned JBL audio system delivers crystal clear sound for music and podcasts. You’ll know exactly where you’re going thanks to a standard Rand McNally navigation system displayed on a monitor that’s larger for 2021. To give you a clear view into your surroundings, you’ll find a tri-view rearview camera system. And to keep you connected, you’ll find a standard in-coach Wi-Fi solution.

Incredible Features

Traveling in style translates through the living space of the Supreme Aire. You’ll find several furniture layout options, including the theater seating opposite a sofa. Others include a chaise lounge, hide-a-bed sofa, a hide-a-leaf table with two fixed and two folding chairs, and more. It’s easy to relax after a long day with a retractable Samsung® 4K LED TV and a Sony® Blu-ray player, plus a Bluetooth® -compatible Bose® 700 soundbar with a 500 series subwoofer. Add the set of three Penguin™ heat pump air conditioners and you’ll have no problem staying comfortable, no matter where you’ll be posting up.

The kitchen in the Supreme Aire makes cooking a dream. Brimming with storage space in beautiful hardwood cabinetry, it’s easy to bring along your most necessary cooking tools. These cabinets also feature self-closing drawers and doors with soft-close hinges. The master suite is built around a king-size bed, adorned with either a plush pillow top mattress or the optional Sleep Number® mattress. Opposite the foot of the bed are a Samsung® LED TV and Blu-ray player. Your floor plan may include a large dresser with several storage drawers with a wardrobe with sliding doors, or two hanging wardrobes and dresser with storage space for clothes, bedding, and other gear. Plus, an optional Splendide® stacked washer and dryer are available to make laundry day easier.

The 2021 Supreme Aire is fitted with a cargo liner, 5/8” floor decking, and 5/8” bead foam. Each Supreme Aire is built on a Freightliner® M-2 112 chassis with a powerful Detroit Diesel DD13 12.8L engine.
