The Entegra Coach Advantage
1. SPARTAN® K3 CHASSIS
Every Spartan® chassis comes with a best-in-class 3-year/50,000-mile transferable warranty, with no deductibles.
Spartan® chassis also boasts an industry-best, 20-year transferable warranty on the frame as well as a Cummins®
5-year/100,000-mile engine warranty and an Allison® 5-year/200,000-mile transmission warranty.
Included in the limited warranty is roadside assistance provided by Coach-Net®, which offers service/towing through
40,000 service and repair facilities in the U.S. and Canada.
2. EXCLUSIVE X-BRIDGE™ FRAME
Our exclusive X-Bridge™ frame adds even more floor strength and structural rigidity, eliminating chassis flex and twisting;
with it, the suspension—not the chassis—absorbs road shock and vibration.
3. FIVE-INCH-THICK FLOORS
The industry’s thickest floor starts with a 3⁄4" 7-ply plywood for dramatic reductions in energy transmission, noise and
vibration. Cabinets are screwed directly to the wood and tile is laid precisely around them; other manufacturers place
cabinets on top of the tile, causing squeaks or cracking.
4. RESIDENTIAL-STYLE WALLS AND ROOF
Our roof combines crowned aluminum truss rafters on 16" centers with Flexfoil®, fiberglass insulation and 3⁄8" plywood
decking. Our sidewalls and rear cap are the ONLY triple-insulated walls on the market. Featuring Styrofoam™, Flexfoil®
and glued batt insulation, our triple-insulated walls keep the coach quiet, and you comfortable, on the inside.
5. KONI® SHOCKS
Custom-tuned Koni shocks on all axles
6. REYCO® GRANNING® PASSIVE-STEER TAG AXLE
The Cornerstone's passive-steer tag axle has a 14,000-lb, rating and a one-touch manual air dump. Disc brakes are featured on every axle.
7. VALID™ 15 IN. DIGITAL DASH
Integrated into the Cornerstones digital dash are a 360° camera, Valid® air leveling system, wireless TPMS and a dual-zone AC/heating system.
8. VILLA® PREMIUM LEATHER FURNITURE
Villa premium leather furniture throughout the Cornerstone includes heated, cooled and massaging driver and passenger seats.
9. ADAPTIVE CRUISE CONTROL
with collision mitigation and blind-spot monitoring.
10. E-Z STEER™ ADJUSTABLE POWER STEERING ASSIST
11. CUMMINS® 605HP ENGINE
12. INDUSTRY'S LARGEST WINDSHIELD
At 120 in., the Cornerstone's windshield is the largest in the industry. Not only does this provide a great view, but it also increases visibility and results in safer travel. Oversized wiper blades add to the safety factor by keeping your view clear in all weather. Fun fact: our windshields are manufactured in Turkey, home of the world's finest sand, to eliminate any distortion in the curved portions of the glass. This windshield delivers the best possible view of the road ahead.
13. CABINETS INSTALLED BEFORE TILE
Every other manufacturer in the motorhome industry tiles their entire floor prior to installing their cabinets and interior walls. This results in driving screws down through the tile, which causes in squeaks and creaks over time. At Entegra Coach, we take a residential approach by installing cabinetry and interior walls directly onto the wood subfloor. We then hand-tile around cabinetry. This takes more time on the production line, but it is an important factor in producing the quietest riding, best handling coach on the market today. Period.
Entegra Coach peace of mind
2-year warranty and 5-year structural warranty
At Entegra Coach, excellence doesn’t end with our stunning interiors and superior craftsmanship. We back each luxury coach with the industry’s highest level of service—including a 2-year limited warranty and a 5-year structural limited warranty.
