Entegra's Flagship Diesel Pusher
The Cornerstone sits at the top of Entegra Coach's Class A diesel pusher lineup. Compared to the Entegra Aspire and Entegra Anthem, the Cornerstone steps up to a larger Spartan chassis, a stronger Cummins X15 engine option, and a top-tier interior treatment featuring hand-laid heated tile floors, cedar-lined closets, home theater surround, and bath-and-a-half floor plans. It's the coach buyers pick when they want Entegra's most appointed motorhome in the current lineup.
Chassis, Powertrain, and Towing
The Cornerstone rides on the Spartan K3 heavy-duty diesel pusher chassis, paired with the Cummins X15 turbocharged diesel available at up to 600 horsepower, one of the strongest engine options available in a production Class A diesel pusher. Standard equipment includes air and hydraulic leveling, air suspension, and an integrated engine brake for controlled descents. The Cornerstone runs a factory 12.5-kilowatt Onan diesel generator standard, which is sized to run the full residential appliance load on shore-cord-equivalent power off the grid.
Cockpit and Driver Technology
Cornerstone cockpit tech includes Smart Wheel integrated steering-wheel controls, an optional Mobileye collision avoidance system, an optional GPS navigation package, and available leather driver and passenger captain's chairs with a passenger-side power footrest for long travel days. Interior touchscreen controls handle coach systems, and an optional iPad control center adds mobile control of lighting, HVAC, and other coach systems.
Exterior
Standard Cornerstone exterior equipment includes full-body paint with high-end schemes drawn from Entegra's signature color palettes, dual awnings for shaded outdoor living, air and hydraulic auto-leveling, exterior storage compartments with lockable slam-latch doors, and a set of exterior amenities Nova can confirm against the current build sheet before publication.
Interior and Master Suite
The Cornerstone interior is Entegra's most appointed build. Standard and available treatments include hand-laid porcelain tile floors with a heated tile system underfoot, ceiling accent features, cedar-lined closets in the master suite, a dedicated Multiplex lighting system in the master with an optional iPad control interface, and a home theater surround sound system tied into the living area. Cornerstone floor plans include a large master shower with hand-laid tile detailing.
Galley
Standard Cornerstone kitchen equipment includes a residential refrigerator, deep cabinets sized to fit household kitchenware, sliding wire racks in select models for pantry organization, and under-sink receptacle placement for small-appliance use. The Cornerstone kitchen is built to residential specifications, which lets owners cook the way they cook at home rather than compromising on RV-scale appliances.
Floor Plans
The Cornerstone lineup includes several bath-and-a-half floor plans (a second half-bath for guest convenience separate from the master), which is a signature Cornerstone feature that sets it apart from lower-trim Entegra diesel pushers. Nova can confirm current Cornerstone floor plan availability on the manufacturer spec sheet before publication.

Entegra Cornerstone FAQs
What is the Entegra Cornerstone?
The Entegra Cornerstone is Entegra Coach's flagship Class A diesel pusher motorhome. It sits at the top of the Entegra lineup and pairs the heavy-duty Spartan K3 chassis with the Cummins X15 turbocharged diesel engine available at up to 600 horsepower. It's aimed at buyers who want Entegra's most appointed motorhome, including hand-laid heated tile floors, cedar-lined closets, and bath-and-a-half floor plans.
What chassis is the Entegra Cornerstone built on?
The Cornerstone rides on the Spartan K3 heavy-duty diesel pusher chassis. Standard chassis equipment includes air suspension, air and hydraulic auto-leveling, an integrated engine exhaust brake, and full air brakes. The K3 is a stronger chassis than the K2 platform used on some mid-tier Class A diesel pushers, and it's sized to handle the Cornerstone's Cummins X15 engine and higher GVWR.
What engine does the Entegra Cornerstone have?
The Cornerstone offers the Cummins X15 turbocharged diesel engine (previously called the ISX) available at up to 600 horsepower, which is one of the strongest engine options in the production Class A diesel pusher category. The X15 is paired with an Allison automatic transmission and delivers the low-RPM torque needed to pull a fully loaded Cornerstone plus a substantial toad vehicle through mountain grades without struggling.
Is the Cornerstone Entegra Coach's flagship motorhome?
Yes. Within the Entegra Coach diesel pusher lineup, the Cornerstone sits at the top, above the Anthem and Aspire. It carries the largest chassis, the strongest engine option, and the most appointed interior treatment in the standard Entegra Class A diesel pusher family.
What is the difference between the Cornerstone and the Anthem or Aspire?
All three coaches are Class A diesel pushers built by Entegra Coach on Spartan chassis platforms, but they occupy different price and equipment tiers. The Aspire is the entry Class A diesel pusher option in the family. The Anthem is the mid-tier build, adding more interior appointments and stronger engine options than the Aspire. The Cornerstone is the flagship, moving up to the larger Spartan K3 chassis, offers the Cummins X15 at up to 600 horsepower, and includes flagship interior treatments like hand-laid heated tile flooring and cedar-lined closets that aren't standard on the Aspire or Anthem.
Does the Entegra Cornerstone come with a bath and a half?
Yes. The Cornerstone lineup includes bath-and-a-half floor plans, which add a second guest half-bath separate from the master bath. That's a meaningful upgrade for full-timers or travelers with guests, since it lets one person use the master bath (typically the larger tiled shower and vanity) without blocking guest access to the toilet.
How much can the Entegra Cornerstone tow?
The Cornerstone's Spartan K3 chassis with the Cummins X15 diesel is engineered to tow substantial loads behind the coach. Typical hitch ratings on Cornerstone builds run in the 10,000-to-20,000-pound range depending on model year and chassis configuration. Confirm the exact tow rating on the specific coach you're considering, since Spartan chassis specifications can vary by build.
Does the Entegra Cornerstone have heated floors?
Yes. The Cornerstone runs hand-laid porcelain tile flooring with an under-floor heating system, one of the signature Cornerstone interior features. Combined with cedar-lined closets, home theater surround, Multiplex-controlled lighting in the master, and available iPad control, the Cornerstone delivers a residential-grade interior experience.
How much does an Entegra Cornerstone cost?
Final pricing on a new Cornerstone depends on the floor plan (including whether it's a bath-and-a-half layout), interior décor package, exterior paint scheme, and engine specification. As Entegra's flagship diesel pusher, the Cornerstone lists at a higher MSRP than the Aspire or Anthem. Motor Home Specialist discounts every new Cornerstone well below MSRP, and used Cornerstone inventory is priced competitively.
