Ben’s Take
We are excited to present this 2026 IWS Signature Series™ Newmar Supreme Aire XT 4505 – "Demo Model" with just 5,661 miles on consignment!
This coach is considered pre-owned as it has been registered and titled. However, it has been barely used. This coach was used for marketing and research and development with Newmar. So we have put a $30,000 "Demo" discount on this unit! This is an incredible opportunity to get a barely used, Supreme Aire that still has its Newmar and Freightliner factory warranties remaining.

A little more about this Supreme Aire XT 4505:
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 $97,000 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:
- Laughton Paint Design with Onyx Blackout Package– We designed this coach to have the Laughton paint design with the Onyx Blackout Package. We saw this shown at the Newmar dealer meeting this year, and it was a showstopper. The blackout package covers the wheels, grill, door handles, mirror covers, and more. This coach looks bad ass! ($15,000 option)
- 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. This also has a 58” tri-fold sofa for opposing seating. ($5,400 in options)
- Sleep Number King Bed – The most comfortable bed option we offer in the Super C lineup. This sleep number bed allows each person to set their own firmness on their side of the mattress. ($2,100 option)
- Electric Radiant Floor Heat– This is an absolute must have option. Nothing better than waking up in the morning with warm tile. Also helps in winter use for 4-season traveling. ($10,000 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 Supreme Aire without this package! ($30,000 option)
- Two-Tone Hardwood Cabinets – For 2026 Newmar is offering a two-tone cabinet design, and we couldn’t say no as its one of the best-looking cabinet designs we have seen in a Super C! This coach has the Summit / Sable Glazed Maple Design with Suede Finish. ($1,800 option)
- Starlink Internet – Satellite Internet with the high-performance wedge mount. Comes built in with a router. Our preferred choice for internet on any motorcoach. ($5,593 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!
