2026 Avalanche 366LS
New 2026 Keystone RV Avalanche 366LS
The New 2026 Keystone Avalanche 366LS delivers luxury fifth wheel living with residential comfort, spacious design, and premium features built for extended travel. Keystone’s Avalanche lineup is known for its upscale interiors, durable construction, and thoughtfully designed layouts that provide the perfect balance of comfort and functionality.
The 366LS floorplan features a popular rear living room layout designed for relaxation and entertaining. Large windows surround the living space, bringing in natural light and providing great views of your campsite. Comfortable theater seating and a tri-fold sofa face the entertainment center and fireplace, creating a cozy space to unwind after a day of exploring.
The kitchen is designed to make cooking on the road simple and enjoyable. A large kitchen island provides additional counter space for meal preparation while the residential refrigerator, cooktop, oven, microwave, and generous cabinetry allow you to prepare meals comfortably while traveling.
The dining area includes a free-standing table and chairs, providing a comfortable residential-style place for meals, games, or working remotely during extended stays.
Toward the front of the fifth wheel, the private master bedroom offers a comfortable king bed along with wardrobe storage and dresser space. This dedicated sleeping area provides a relaxing retreat at the end of the day.
The spacious bathroom includes a large residential-style shower, vanity sink, and additional storage, delivering the comfort and convenience expected from a luxury fifth wheel.
Outside, the Avalanche continues to impress with large pass-through storage compartments for camping gear and travel essentials. A power awning creates a shaded outdoor living area where you can relax, entertain guests, or enjoy evenings at the campground.
With Keystone’s attention to quality and residential-style comfort, the Avalanche 366LS is an excellent fifth wheel for travelers who want a spacious RV designed for both weekend adventures and extended camping trips.
