What makes the 378MBS interesting is its layout logic: the living room lives in the rear slide, giving it a true room-like feel, while the east/west bed up front stays well away from the noise. The mid-bunk section is legitimately versatile. Owners have used it as an office, guest space, or actual bunk room depending on the trip. Grand Design builds the Solitude line with thicker walls and more insulation than most competitors, and the 378MBS adds CRE 3000 suspension and auto-leveling to help manage what is a substantial rig to tow. A kitchen island, desk, fireplace, and washer/dryer prep mean this one is set up for extended stays, not just weekends.
