2026 IWS Signature Series™ Newmar Summit Aire 4505 – Stock #8454

On Order – Arriving October 2025

A little about this Summit Aire 4505: 

We are so excited to announce the Newmar Summit Aire! This is the top of the mountain from Newmar with their Super C Lineup. Ever since we signed up with Newmar in 2021, we have been dreaming of this model to come into existence. 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. Welcome to the Summit!

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.

Being an IWS Signature Series™ build, we picked over $73,000 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:

• Custom Designed Interior Upgrades Through Newmar Specials Program– We hand picked this interior with Newmar. We didn’t want to just offer what comes standard. We wanted to offer something unique, and one of one. This coach interior offers that. We hand selected the counter tops, backsplash, tile in the bathrooms, the tile flooring, and even the Italian leather furniture. ($11,000 in custom design options)

• 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 Summit 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. ($3,500 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!
