About Product
The 2016 Entegra Cornerstone 45B stands as one of the most refined and powerful luxury coaches ever produced, combining unmatched engineering, superior comfort, and sophisticated design into a 45-foot masterpiece.
Powered by the 600-horsepower Cummins ISX 15L engine and built on the Spartan K3 tag-axle chassis, this all-electric motorhome delivers not only incredible power and towing capacity, but also a ride quality comparable to a high-end touring bus.
With just 10,000 miles, this example has seen limited use and retains a like-new appearance throughout. Inside, every surface reflects Entegra’s commitment to excellence — from Natural Cherry hardwood cabinetry to heated high-gloss porcelain tile floors, Quartz countertops, and top-tier entertainment systems.
This model’s 45B floorplan includes a full bath and half-bath, a residential galley, and a spacious living area outfitted with luxury seating, integrated fireplace, and custom lighting — creating a mobile environment that feels more like a penthouse than a motorhome.
