About the price: Lowest list price (45B and 45Z) as published by RVGuide.com for the 2026 model year (https://www.rvguide.com/specs/entegra-coach/class-a/2026.html); 45D, 45R and 45V $988,980. The builder's page shows no price. This is RVGuide.com's own suggested list price, not a builder price list. The guide lists prices by model year but gives no publication date and does not say what they cover (base or as-equipped).
These values describe this model year and configuration. An individual coach can differ, so check it against the coach’s own records. “Not documented” means the encyclopedia does not have that fact yet.

Notes
Torque is rated at 1,150 rpm. Front axle 20,000 lb with independent front suspension; Dana rear axle 20,000 lb; Reyco Granning tag axle 14,000 lb; 15-gallon DEF tank. The builder's page lists an exterior length of 45 ft 5 in, while RVGuide lists 44.92 ft (44 ft 11 in), the figure Entegra's own 2018 brochure gives for 45-series floorplans; length is left blank in this overview and in the 45B and Reserve 45D records until a 2026 spec sheet settles it. Tank capacities are not on the builder's page; RVGuide shows 100/62/41 gallons for the 45B. No 2026 Cornerstone brochure was found online; the builder's page links only an owner's manual. The builder's page names a Cummins 12,500-watt generator and lists chassis standards and options, but it does not name a heating system, air conditioners, inverter, batteries or solar panels, so none are listed here.
