2026 Entegra Cornerstone 45D
Live out your dreams in ultimate luxury in the Cornerstone, Entegra Coach's flagship diesel pusher and the #1 selling coach in the 605HP engine category.

Built utilizing unique construction techniques and offering numerous ride and handling upgrades, the Cornerstone is truly the quietest riding, best-handling coach on the market today—period. Premium interior features and materials take this powerful motorhome to the next level. The Cornerstone is the epitome of power meets luxury.
The Cornerstone is built upon the Spartan K3 or Freightliner SL chassis. Both chassis features a Cummins 605HP engine, side-mounted radiator, custom-tuned Koni shocks and the Valid™ Truline air leveling system for a powerful and smooth ride you won't find anywhere else.
Inside the cockpit, our cab-forward design features a 120-inch windshield, the largest in the industry, for an immersive view of the road. With a heads-up design, the newly updated Safe View dash features a 15-inch digital dash, 15-inch center console infotainment center and tri-pod steering wheel to keep everything at your fingertips while keeping your eyes on the road and hands on the wheel. Heated and cooled Italian leather cockpit seats with massage function will keep you nice and comfortable. At the same time, safety features include a collision mitigation system with blind-spot monitoring and the Delta Mobile Systems® aiDARS™ 1X active 360° surround view system. All these amenities allow the Cornerstone to deliver the best driving experience in the industry.
The Cornerstone's living space offers options in wood, décor, and tile color so you can build the coach of your dreams, regardless of your taste. Luxurious Italian leather furniture throughout, hand-tiled floors, backsplashes and showers, premium residential appliances, and custom-built hardwood cabinetry give the Cornerstone interior an unmatched look and feel.
While the Cornerstone is stunning inside and out, what makes it extraordinary lies beneath the surface. With residential hung-wall construction, 5-inch-thick wood floors, cabinets laid before tile installation and three layers of insulation, the true beauty of the Cornerstone is the incredible quality of its hand-built construction. These construction features add to the quiet ride of the Cornerstone and allow us to offer our customers the best warranty in the industry. With a two-year limited and 5-year structural warranty, you will feel true confidence and security in your Entegra Coach Cornerstone.
