The 2026 Forest River RiverStone 39RKFB is a high-end luxury fifth wheel built for full-time RV living, featuring a rear kitchen layout, bath-and-a-half configuration, and four slide-outs that create an expansive residential-style interior. Designed on a heavy-duty chassis with premium insulation and high-capacity systems, it delivers maximum space, storage, and residential comfort for extended travel or long-term stays.

Inside, the rear kitchen is the focal point, offering wraparound counter space, residential appliances, and extensive cabinetry for true home-style cooking on the road. The main living area features opposing slides that open the coach significantly, along with theater seating, entertainment center, and a dedicated workspace area depending on configuration. The bath-and-a-half layout adds convenience for guests while keeping the master suite private and fully equipped with wardrobe storage and washer/dryer prep or installation.

The front master suite provides a true residential sleeping experience with a king bed, full wardrobe storage, and direct access to the primary bathroom. Throughout the coach, premium materials, integrated smart controls, and high-end finishes elevate the overall feel. Large holding tanks, multiple air conditioners, and upgraded insulation support extended-season camping and off-grid capability when needed.

Exterior features emphasize durability and convenience with full pass-through storage, power awnings, advanced leveling systems, and upgraded suspension designed for stability during long hauls. The RiverStone line is positioned as Forest River’s premium luxury fifth wheel segment, focusing on residential comfort and long-term livability.
