The Entegra Coach Cornerstone 45B is built around a bath-and-a-half floor plan with a rear full bath, but the powertrain and systems list is what really sets it apart. The Aqua-Hot 600D hydronic system delivers in-floor heat throughout the coach while also preheating the engine, and the 12,500W Onan diesel generator rides on a powered slide-out tray with automatic start for stress-free boondocking. A Victron 3,000W pure sine wave inverter, four L16 AGM batteries, and dual 200W solar panels round out a serious off-grid package. Owners consistently praise the Cornerstone 45B's ride quality and quiet cabin, crediting the Reyco Granning independent front suspension and custom-tuned Koni shocks, and the general sentiment from those who've bought one is straightforward: they'd do it again.
