The 2026 Forest River RiverStone 425FO is a flagship luxury fifth wheel designed for full-time RV living with a residential focus, offering a massive front office / front living layout, six slide-outs, and premium four-season construction. Measuring approximately 45 feet long with a 24,000 lb GVWR, it delivers maximum interior space, heavy-duty towing stability, and high-end residential comfort for long-term travel or stationary living. It is built with advanced insulation, dual A/C systems, and high-capacity tanks for extended stays in all climates.

Inside, the 425FO is designed like a luxury apartment on wheels. The front office/living area configuration creates a dedicated workspace or entertainment zone with theater seating, large entertainment center, and premium sound system. The opposing slide-outs in the main living area create an open-concept floorplan with wide walking space, residential furniture, and high-end finishes throughout. A full kitchen includes residential appliances, solid-surface countertops, large pantry storage, and a layout designed for extended cooking and storage needs.

The rear master suite provides a private retreat with a king bed slide-out, full wardrobe storage, and washer/dryer prep or installation, offering true residential functionality. The bathroom includes a large shower, porcelain toilet, and upgraded fixtures designed for long-term comfort. A half-bath in select configurations enhances convenience for guests and reduces congestion in the main living area.

Built for extended-season and full-time use, the RiverStone 425FO includes a high-capacity furnace, dual or triple air conditioning system, heated holding tanks, and advanced insulation package. Exterior construction features fiberglass sidewalls, a fully enclosed underbelly, multiple power awnings, and hydraulic leveling for quick setup. The chassis and suspension system are engineered to handle the weight and scale of a true luxury fifth wheel.

Technology and comfort upgrades include a smart control system, residential entertainment package, inverter power system, solar prep, and advanced connectivity options, making it suitable for both off-grid capability and luxury campground living.
