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.

At nearly $440K off MSRP, this low-mileage 2022 Cornerstone 45B is one of the more compelling buys in the luxury diesel pusher market right now. With only 23,165 miles on it, the heavy lifting of that initial break-in is done, and Entegra's reputation for handling warranty issues promptly means any early gremlins have likely already been sorted.
The 45B's rear bath layout gives you a genuinely private master suite feel, and owners consistently rate this floorplan among the best in its class — it's the kind of space that makes you forget you're in a motorhome. The outdoor entertainment setup extends that living space outside, while the bath and a half configuration keeps morning routines from becoming a bottleneck.
Entegra builds these coaches with a quiet, planted ride that sets them apart from most Class A competition — owners rate drivability near the top of the segment. If you're covering serious miles between destinations, that matters more than almost anything else.
