## Overview

The Cornerstone 45Y sits at the top of Entegra's lineup for good reason, pairing a Spartan chassis with independent front suspension, a passive-steer tag axle, and Bilstein shocks front and rear for a ride that owners consistently describe as car-like for a 45-foot coach. Aqua-Hot hydronic heating delivers in-floor warmth throughout the cabin while also preheating the engine, and the dual 3,000-watt pure sine wave inverters backed by four L16 AGM batteries mean serious off-grid capability. Outside, dual Girard Vision dual-pitched patio awnings with LED lighting, a 43-inch Samsung 4K TV with a Bose soundbar on a swivel arm, and Executive Bus Armor stainless-steel trim give the Cornerstone 45Y a presence that matches its mechanical spec. One verified owner, on his fifth Entegra Cornerstone, called it the best value in high-end motorcoaches and singled out both Entegra and Spartan's factory support as standouts.
