Ben’s Take
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 20,000 lb. towing capacity with a single rear axle 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 desirable, 38’ in total length, and features the 3827 mid-bath floorplan. Newmar has always set the bar by thinking differently and out innovating the competition. We love that you can fit, a stacked washer and dryer, a true king bed, a nice size bathroom, a large living area, a pantry, and a nice kitchen. We designed this one with Newmar’s Cab Over Bunk for extra sleeping and storage over the cab! Now available for Supreme Aire!
Being an IWS Signature Series™ build, we picked over $96,000 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:
- All White Single Color Paint Design with Onyx Blackout Package– We designed this coach to come in an all-white paint design with the Onyx Blackout Package. We love customizing, and so do our customers. The blackout package covers the wheels, grill, door handles, mirror covers, and more. This coach is going to look bad ass! ($18,000 in customizations)
- 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. ($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)
- 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 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!
