2026 IWS Signature Series Newmar Summit Aire 4505 – Stock #8498

Unit is In Stock!

A little about this Summit Aire 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 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.

Being an IWS Signature Series build, we picked over $77,000 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. T

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)

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 / Sedona Glazed Maple Design with Suede Finish. ($2,471 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!

Full-Wall Slide
King Bed Slide
Euro Booth Dinette
Full Rear Bath
Wardrobe/Flip-Up Bunk

With triple slides including a full-wall slide, this spacious coach will feel just like home! This model layout resembles 4505, but you'll enjoy the added wardrobe/flip-up bunk within the full-wall slide for added sleeping and storage space. Once you arrive at your destination, lunch can be made on the all-electric induction cooktop or in the stainless steel convection microwave. There is a Euro booth dinette (non-sleeper) where you can dine together, and you'll find additional seating space on the hide-a-bed sofa. The mid-coach half bath will be easily accessible to use during the day, and a full rear bath will let you freshen up in the evening. Here, you'll find a 40\" x 30\" shower with a seat and two wardrobes for towels and clothes. And don't overlook the master bedroom with its king bed slide, dual shirt wardrobes, a dresser, plus a Samsung LED TV to watch movies in bed!

With any Summit Aire Super C diesel motorhome by Newmar, you will experience what happens when power meets luxury! The Freightliner Cascadia chassis provides a strong and durable foundation to your coach, and there is a 30,000 lb. rear hitch for towing your family car along. A full-paint Masterpiece Finish with cut and buff is ultra sleek, and the smart level hydraulic leveling jacks with a Bluetooth compatible touchpad will have you set up at the campground in no-time. You will stay powered up by the eight 6V AGM house batteries, 12.5 kW Cummins Onan diesel generator, and 3000W Pure Sine inverter, plus there is an energy management system to monitor power usage. There are super polished solid surface countertops in the kitchen, bedroom, and bathroom, and you're sure to appreciate the electric radiant heat installed below the floor tile for added comfort. Additional interior comforts include an Aqua Miser shower system, air ride captain's seats, a plush pillow top mattress, a central vacuum with a tool kit, and the list goes on!
