RV Power and Performance

The Cornerstone by Entegra is built on a Spartan® K3 raised-rail chassis and is powered by a Cummins® 15 liter X15 turbocharged 605 HP diesel engine with an Allison® 4,000 MH 6-speed transmission. The Cornerstone also features a side-mounted parallel-airflow radiator, 210 amp alternator, 1,500W engine block heater, and two 12V chassis batteries. With automatic traction control, three-stage engine brake, and all-wheel ABS disc brakes, safety is integral in this RV’s design. The Reyco Granning front axle and rear axle built by Dana both have a 20,000 lb. rating and the rear axle ratio is 4.30. The tag axle from Reyco Granning is a passive-steer axle with air dump and rated at 14,000 lb. A remote air connection and tire pressure monitoring system including temperature monitoring are handy features for added convenience while on the road. Independent front air suspension and Bilstein shocks assure a smoother ride with 60mm shocks on the front axle and 46mm shocks on the rear and tag axles.

The Equalizer hydraulic automatic coach leveling system and Valid Truline air leveling system with auxiliary air compressor can’t be overlooked as examples of the top of the line choices Entregra made when building this motorhome. For boondocking or when on the road, the Onan 12,500W diesel generator with automatic start provides plenty of power for your needs. The 150 gallon fuel tank has dual fills and the generator is mounted on a powered slide out for easier access during maintenance. Optional solar panels can extend your power capabilities with dual 100W roof mounted panels. The power features on the Cornerstone also include a smart automatic transfer switch with surge protection, 3,000W pure sine wave inverter, four L16 AGM batteries, and a 50 amp shore power cord on an electric powered reel.

With three 15,000 BTU A/C units with heat pumps and a condensation drain system, keeping cool in hot summer months is no problem for the Entegra Cornerstone. When on an adventure in the cooler months, the Aqua-Hot 450D hydronic water and heating system with engine preheat, basement storage, and in-floor heat throughout keep you and your family comfortable while enjoying the serenity of snow capped mountains.

The city and tank water filtration system ensure a higher quality of water throughout the coach. As for the black tank management, a Sani-Con macerator system with power gate valves, manual backup, and sprayer provide ease of use and an increased reliability. There’s more possibilities with the Cornerstone and its 20,000 lb hitch with 7-pin plug enabling adventurers to bring all their favorite recreational vehicles with them on their next road trip. Entegra also included the Spartan Safehaul tow vehicle brake system to provide a safer towing experience.

Entegra Cornerstone Exterior

Entegra Cornerstone measures up at 45’ 5” in length and has eight modern Sikkens custom full-body paint options adorned with 10” stainless-steel trim accents and Diamond Shield front protective film mask. LEDs are used on all the exterior lighting, including low/high beam headlights, fog lights, daytime running lights, brake lights, docking lights, and accent lights which are even placed underneath each passenger slideout room. With frameless dual-pane tinted safety glass windows, the cab stays cooler during the day and makes for an aesthetically pleasing appearance. Chrome side view mirrors give the coach a classic look which are equipped with safety features like remote control, heating, blind-spot indicators, and integrated cameras. The lit grab handle includes a modern touch with the internal light, doorbell, and keypad system for keyless entry. 

Entegra built the Cornerstone with top notch engineering, the X-Bridge bracing is welded to the chassis frame for added stability and reduces wear on the chassis from road vibration and shock. The floor is built on 2” by 4” wood trusses topped with ¾” 7-ply plywood decking, while the exterior walls are built with 2 ½” Aluma-Tru welded tubular aluminum studs and the roof is 4” thick arched aluminum trusses topped with ⅜” plywood decking and a one-piece fiberglass roof. The floor, exterior walls, and roof are then filled with batt and Flexfoil insulation. Cornerstone’s reinforced frame and layered insulation creates not only a safer RV but also a quieter and smoother ride for you and your loved ones to enjoy.

Luxury flows from the floorplan of the Cornerstone to the appliances and finishes chosen by Entegra, making this a one of a kind Class A RV. With four large slideouts, there is a comfortable immensity to its interior, allowing for more options, features, and space than most motorhomes on the market. The central vacuum system and hand-laid porcelain tiled floor throughout, give a residential functionality and feel. Powered solar day and blackout night shades are a convenient necessity. Intuitive motorhome functionality meshes with residential splendor for an unparalleled camping experience in the Entegra Cornerstone.

The living space varies for each model but all create an inviting spacious area for socializing and enjoying time with family. There are two Samsung QLED 4K UHD Smart TVs in the living area, the 32” TV is located above the cab in the front of the coach while the 50” is located in slightly varying spots depending on the model.

RV Kitchen

If you enjoy making gourmet meals and hope to make as few compromises as possible when it comes to the kitchen in your RV, the Cornerstone is likely the RV for you. With an impressive amount of counter space, preparing a meal for a large group of hungry friends and family members is a breeze. Even clean up time is kept to a minimum with the Fisher & Paykel dishwasher. You can store more produce than most campers in the Whirlpool stainless-steel residential refrigerator which even has an ice maker and water dispenser. A two burner induction cooktop had a matching wood cover when it’s not in use. Solid-surface countertops are accompanied with LED accent lighting for greater visibility.

The Blanco single-bowl granite sink and porcelain tile backsplash are beautifully done, contributing to the overall functionality and residential feel of this magnificent kitchen. The Whirlpool 1.9-cu.ft. convection microwave oven and slide-out storage trays in the overhead cabinet are necessities we won’t overlook. A unique feature for most of the models of the Cornerstone is an easy access trash chute accompanying the large, deep waste basket drawer. Cooking should be enjoyable, especially when on vacation, Entegra made that possible with this expansive kitchen design. But, if the day starts to wear and you’re in need of a libation to help induce a more mellow demeanor, they’ve covered that too with the bar area and beverage cooler included on select models.

RV Bedroom and Bathroom

Entegra’s Cornerstone may have the most residential-like features of any RV we’ve covered thus far. This trend continues as we pass through the kitchen towards the rear of this immaculate motorhome. For instance, most of the Cornerstone models feature a half bath in the hallway leading to the bedroom, a feature uncommon for a camping experience.

The main bath boasts a large shower with porcelain tiled walls and floor enclosed with a frameless glass shower door. A teakwood shower seat and pivoting shower head with hand-held spray wand add to the shower’s functionality. A dual sink vanity is included on most models as well as an oversized walk-in wardrobe closet. Each model includes a Whirlpool stacked washer and dryer and abundant storage. Relaxation is the number one priority in the Cornerstone’s bedroom, as seen with the king-size Select Comfort Sleep Number bed and 32” Samsung QLED 4K UHD Smart TV with Bose sound bar.
