This fifth wheel is decked out in luxuries! The full rear bathroom has a walk-in shower to freshen up in each morning, a dual sink vanity for two to get ready at once, and an area prepped to add an optional washer and dryer. You will enjoy a good night's rest on the king bed slide inside the private bedroom and others can sleep on the opposing tri-fold sofa sleeper slides once they are converted. There are two kitchen pantries to hold everyone's favorite snacks, one of which is a walk-in pantry. The 18 cu. ft. residential refrigerator will keep your perishables fresh and you also have the option to switch it out for a 19.6 cu. ft. 12V refrigerator instead. The front living area has a front entertainment center with a 40" fireplace and a 50" TV, plus there is Thomas Payne theater seating with massage, heat, LED lights, and a USB charging station to keep your electronics charged while you relax!

 

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!

 

A 5 year protection plan can be added to this camper for $5,770 or $47/mo*. Ask our team for details!
