2026 IWS Signature Series™ 38’ Newmar Supreme Aire SE 3827 – Stock #8465

On Order – Arriving October 2025

A little about this Supreme Aire SE 3827: 

It’s the moment we have all been waiting for. The 2026 Newmar Supreme Aire SE is now built on the Freightliner P4 Cascadia chassis! After years of waiting, it’s finally here, and we couldn’t be more excited!

We are proud to present the Supreme Aire SE as an IWS Signature Series™ build. When you see the IWS Signature Series™ label, you know that it’s the best of the best. Built on the Freightliner P4 Cascadia 116 chassis, mated with the Detroit Diesel DD13 Engine with 525hp 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.

Being an IWS Signature Series™ build, we picked over $92,000 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. ($3,500 in options)

• 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)

• 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 10% 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!
