Class a motorhomes that share features with the Cornerstone 45Z, like outdoor entertainment and rear bedroom.
The 605-hp Cummins engine paired with the Spartan K3 chassis is the first thing owners mention. This thing genuinely drives like a much smaller vehicle, helped along by independent front suspension, custom-tuned Koni shocks, and a three-stage engine brake on mountain descents. Inside, the Aqua-Hot 600D hydronic system handles both the hot water and in-floor heat throughout, so the coach stays comfortable without ever firing up electric space heaters. The rear bedroom layout keeps the living area wide open, and the outdoor entertainment setup. Including a 43-inch Samsung QLED with JBL soundbar mounted outside. Means the fun doesn't stop when you step off the coach. Serious infrastructure backs all of it up: a 12,500W Onan diesel generator on a powered slide-out tray, 400 watts of solar, a Victron pure sine wave inverter, and four L16 AGM batteries give you genuine off-grid capability at this price point.
