NEW 2025 Grand Design Solitude Fifth Wheel 388MBS

Built for families, extended stays, and travelers who refuse to compromise on space or comfort, the 2025 Grand Design Solitude 388MBS delivers true residential luxury wrapped in a road-ready fifth wheel. With four slide outs and a thoughtfully designed multi-room layout, this Solitude creates distinct living zones so everyone can relax, work, or unwind without feeling crowded.

Step inside and you’re immediately welcomed by the rear living area, a perfect gathering space after a day of adventure. An L-shaped sofa, theater seating, and a free-standing dinette offer plenty of seating for conversation, game nights, or movie marathons. The entertainment center features a telescoping TV, fireplace, and an electronics drawer designed to keep phones, tablets, and laptops charged and organized.

The middle den/bunkroom adds incredible versatility. Whether you need extra sleeping space, a guest room, or a mobile office, this room delivers with a tri-fold sofa, bunk above, dresser/desk combo, and a large 50"" TV. It’s ideal for kids, guests, or remote work on the road.

Up front, the private master bedroom is your personal retreat. A queen bed slide out opens the room, while the expansive front closet includes a built-in hamper and washer/dryer prep for extended travel convenience. The dual-entry bathroom connects directly to the bedroom and features a shower with a seat, making it both comfortable and accessible.

The kitchen is designed for serious cooking and everyday ease. An L-shaped counter provides generous prep space, complemented by a 20 cu. ft. refrigerator, pull-out trash cans, ample cabinetry, and residential-style finishes that make meal prep feel effortless whether you’re camping for a weekend or a season.

Outside, two power awnings extend your living space, creating shaded areas perfect for relaxing, entertaining, or enjoying the view at your favorite campsite.
