The ALL-NEW 2026 Keystone Cougar Premium 316RLS proves why Cougar is the #1 selling fifth wheel in North America. This 35'8" three-slide floor plan is built around a spacious rear living room that keeps the social hub of the coach at the back — away from the kitchen traffic and bedroom — creating a natural, residential flow throughout. A private king bed anchors the front bedroom, while the mid-ship oversized bathroom features a full glass door shower with skylight, residential vanity cabinetry, and a linen cabinet that makes extended trips genuinely comfortable. The Umber Luxe interior decor brings warmth and sophistication with shaker-style hardwood cabinet doors, soft-close hidden hinges on every drawer and cabinet, solid surface countertops, and a high-rise chef's faucet over a black stainless undermount kitchen sink — details that set this coach apart from the competition the moment you step inside.
Built on Keystone's exclusive HyperCore™ composite wall construction and an individually engineered structural I-beam chassis, the 316RLS is designed to hold up trip after trip without compromise. The heavy-duty 6,000 lb. axles with ABS brakes deliver confident stopping power and added safety on any road, while the High Performance Road Armor™ shock absorbing equalizer smooths out the miles. A pivot-hinge entertainment center with hidden pantry adds clever storage right where you need it, and the full pass-through storage compartment — equipped with LED lighting, power outlets, and TV hookups — gives you the kind of gear capacity that serious campers depend on. This unit is finished in the striking Midnight Edition Full-Body Black Onyx Paint package, paired with custom aluminum luxury wheels, giving it a bold, head-turning presence at every campground and on every highway mile between.
This unit arrives fully loaded for all-season, off-grid adventure. The Cougar Innovation Package brings Solar Flex Discover and two 100Ah DFE heated lithium batteries for self-sufficient power management, while the Climate Guard protection package, dual-heated holding tanks, and insulated slide floors extend your camping season well beyond fair weather. Dual A/C units — a Furrion 18K BTU Chill Cube and a 15K BTU ducted bedroom unit — keep every corner of the coach cool in summer, and the electric 4-point auto levelling system gets you set up fast. Whether you're a weekend warrior or a full-season traveller, the 316RLS delivers the layout, the build quality, and the features to make every trip better than the last.
