Underbed Storage
Rear Kitchen
Dual Entry Doors
Fireplace
Outdoor Kitchen

With a bath and a half, it's a clean decision to take this fifth wheel with you on your next camping trip! One of the dual entry doors leads directly into the rear kitchen which has a large pantry and an 18 cu. ft. residential refrigerator to store your food items. The free standing dinette and tri-fold sofa sleeper slide and opposing tri-fold sofa sleeper slide opens up the middle living area for more interior space. The half bathroom is conveniently located straight in through the main entry and features washer and dryer prep for clean clothes throughout your entire trip. The master suite not only has a king bed slide with storage underneath and a bench next to a dresser, but also access into the front full bathroom which has a dual sink vanity, a shower with a seat, and a toilet with privacy walls!

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 exterior also includes an outside shower with hot and cold water, Lippert strut assisted SolidSteps, Hitch Vision with LED lighting, and many more conveniences!
