You’re going to be captivated by the massive front living room and the wide-body residential elegance of the New 2025 Keystone RV Sprinter 3670FLS! As a premier "Front Living Specialty" (FLS) model, this fifth wheel is specifically designed to provide a sophisticated entertainment space that feels like a stationary luxury home. You’ll love the stadium-style front lounge, featuring dual opposing tri-fold sofa slides and plush theater seating that face a massive LED TV and a crackling electric fireplace. Because it is built on a 100-inch wide-body chassis, the interior volume is breathtaking, offering extra walking room and deeper slides that you’ll notice the moment you step inside!

The 3670FLS is a masterclass in culinary design, boasting a central "island kitchen" with solid-surface countertops, a deep-seated professional-grade sink, and a high-efficiency 12V residential refrigerator. The transition to the rear master suite is seamless, leading you to a private sanctuary with a King-size bed slide-out, a second vanity, and a massive walk-in closet prepped for a washer and dryer. Whether you are hosting friends for a big game or enjoying a quiet evening in the master retreat, the high-gloss fiberglass exterior and modern farmhouse interior ensure you’re traveling in the height of style!
