New 2025 Keystone ALPINE FW 3910RK

 Luxury is not an option, it is a standard with each one of these Keystone RV Alpine fifth wheels! A 8' 4" wide body construction will create an open, residential feeling, and cutting-edge technology will provide a hassle-free camping experience. The Tru-Fit slide construction is more durable and minimizes motor structural stress, as well as resists leaking, and the Blade Pure airflow system provides residential comfort with its high-performance. Each fifth wheel includes designer flooring throughout, stunning solid wood cabinet doors, luxurious crown molding, and solid surface countertops in the kitchen. The SolarFlex Protect 200 comes standard or you can choose the optional SolarFlex Discover 440i for even more off-grid capabilities. The exterior also includes an outside shower with hot and cold water, Lippert strut assisted SolidSteps, Hitch Vision with LED lighting, and many more conveniences!
