## Overview

At 45 feet on a Freightliner M-2 112 chassis, the Supreme Aire 4530 blurs the line between Super C and high-end diesel pusher. Owners consistently note the air-ride cab delivers a ride quality that surprises people who've only driven traditional Class C motorhomes. The rear bath layout puts a full master suite at the back with real separation from the living area, and the bath-and-a-half setup means the half bath up front handles traffic without anyone trekking through the bedroom. Three 15K BTU heat pump units keep things comfortable, and if you opt into the 960 AHR lithium system with dual 3000-watt inverters, you can run the air conditioning off battery well before the Onan 12.5kW diesel ever needs to wake up. Newmar finishes this one with gelcoated fiberglass sidewalls, full-paint Masterpiece graphics, stainless exterior trim, and hydraulic leveling jacks. The kind of build quality that backs up their famously low warranty claim rate.
