Description
Step into luxury, comfort, and proven value with the Pre-Owned 2021 Grand Design Solitude 310GK—a highly sought-after fifth wheel that blends residential elegance with road-ready performance. Designed for extended stays and full-time living, this rear living floorplan offers the perfect combination of space, functionality, and upscale features at a more accessible price point.
Measuring just under 35 feet with three slide-outs, the 310GK delivers an open-concept layout that feels spacious and inviting from the moment you walk in.

The rear living room is a standout feature, offering plush theater seating, a tri-fold sofa for guests, and a large entertainment center with a fireplace—perfect for cozy evenings after a day of adventure. High-end finishes like hardwood cabinetry, solid surface countertops, and designer accents elevate the interior, making it feel like a luxury condo on wheels.
At the heart of the coach is the gourmet kitchen, built for those who love to cook on the road.
