Ben’s Take

A little about this Supreme Aire 4505: 
We are so excited to announce the Newmar Supreme Aire! We wanted to offer our customers the most luxurious experience possible and combine it with that Super C driving experience we know and love. We can tell you that Newmar absolutely nailed it with this one. This is the most luxurious coach we offer. 
 
Built on the Freightliner P4 Cascadia 126 chassis, mated with the Detroit Diesel DD16 Engine with 600hp and 1,850 ft lb. of torque. We ordered this one with the Detroit DT12 12 Speed Automated Manual Transmission which is our favorite transmission for towing performance. Speaking of towing, this coach features a 30,000 lb. towing capacity with tandem rear axles leading the way. This is a beast of a powertrain that can handle anything you throw at it. It also has the Detroit Safety Assurance collision mitigation system, that features lane departure warning, blind spot monitoring, adaptive cruise control, and adaptive brake assistance.
 
This coach sits at a 45’ in total length, and features the 4505 bath and a half floorplan. This is our favorite 45’ Floorplan out there. We call this the “Epic” floorplan. This floorplan is excellent for those that want to go to a destination and stay for a while. We love the amount of seating options with the euro booth dinette, the theater seats, and the opposing sofa. There is so much room in this coach!
 
Being an IWS Signature Series™ build, we picked over $107,000 in options on this one. Some of these options we ordered are through the Newmar Specials program, which you can’t get on the standard option sheet. A few of the major options include:
 
  • Theater Seating and Euro Booth Dinette in lieu of Sleeper Sofa and Dinette – A personal favorite combination of ours. We designed this floorplan for couples that are looking for the most luxurious, comfortable floorplan on the market. The theater seats are the most comfortable seats for the Supreme Aire, and we love the Euro Booth versatility where if you do have 4 people over for dinner one night, its easy to convert to 4 seats. ($6,500 option)
 
  • Lithium Battery Upgrade Package – This gives you 940-amp hours of lithium batteries, and (2) 3,000-watt inverters over the standard 6-volt batteries, and single inverter. We wouldn’t order a Summit Aire without this package! ($30,000 option)
 
  • IWS Signature Series™ Solar Panel Package (3) 220 Watt Panels  – We know that if you are interested in a Super C you are also interested in boondocking! We install our own Solar Panel System giving you 660 Watts of solar in conjunction with the Lithium. We install (3) 220 Watt Panels that are hard panels compared to the stick-on panels that don’t perform nearly as well! ($5,800 option)
 
  • Starlink Performance Internet – Satellite Internet with the high-performance wedge mount. Comes built in with a router. Our preferred choice for internet on any motorcoach. ($5,400 option)
 
 
You can put your name on it with a $5,000 deposit. Give us a call, and we can tell you even more about it, and the process of making it your coach. See you out on the road!
