A little about the 2026 Newmar Summit Aire
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.
