The 2026 Grand Design Solitude 390RK is a luxury fifth wheel designed to give RVers expansive interior space, upscale finishes, and extended-stay capability. At approximately 42’5? long with five slide-outs, this wide-body fifth wheel feels open and well-organized for families, couples, or full-timers.

This model’s rear kitchen layout separates the cooking and prep area from the living space, maximizing flow and counter room. With a raised bar top and oversized pantry, meal prep and entertaining are both functional and comfortable.

The mid-living area centers around comfort and entertainment, featuring dual tri-fold sofas, theater seating, a large LED Smart TV, and an electric fireplace. Panoramic windows let in natural light, enhancing the open feel of the living space.
