Newmar Summit Aire Super C diesel motorhome 4505 highlights:

Full-Wall Slide
King Bed Slide
Euro Booth Dinette
Spacious Kitchen Pantry
Full Rear Bath

With triple slides including a full-wall slide, this spacious coach will feel just like home! 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 spaces on the hide-a-bed sofa and jack-knife 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 retracting 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!

Great Service!
The crew at Midway are the greatest people. Chad is the go to guy if you looking for a new or used Motorhome. Service is always done right at a fair price. Dave is always helpful.

Allen
Great experience!
HUGE thanks to Chad for helping us find the perfect RV for our trip out west! He completely understood our needs as well as our budget. He went out of his way to find exactly what we needed instead of getting close enough for a quick sale. This guy is fantastic at what he does and we strongly recommend
