The 2026 Forest River RiverStone 39RKFB is a luxury rear-kitchen fifth wheel designed for full-time RV living, offering a residential experience with a bath-and-a-half layout, four slide-outs, and premium construction materials. Built on a heavy-duty chassis with high-capacity suspension and insulation, it delivers stability on long hauls while maximizing interior space and comfort for extended stays.

The rear kitchen layout is the centerpiece, featuring expansive counter space, residential-grade appliances, and deep storage designed for serious cooking on the road. The main living area opens dramatically with opposing slides, creating a wide, open floorplan that includes theater seating, entertainment center, fireplace, and a dedicated workstation setup. This configuration supports both relaxation and remote work without sacrificing living space.

The front master suite is built for residential comfort with a walk-around king bed, large wardrobe storage, and direct access to a spacious bathroom. The additional half bath adds convenience for guests and reduces congestion in the main living area. High-end finishes, solid surface countertops, and integrated smart controls elevate the interior feel throughout the coach.

Exterior construction emphasizes durability with a fiberglass body, advanced leveling system, large pass-through storage, and multiple power awnings. Climate control and tank capacities are designed for extended-season or off-grid use, making this model well-suited for long-term travel or full-time RV living.
