This rear kitchen fifth wheel makes extended stays or weekend trips to the lake enjoyable! The chef of your group will find plenty of counter space with the included kitchen island, plus there is a pantry and 18 cu. ft. residential refrigerator for food storage. A free-standing dinette provides a place to dine together, and the largest L-shaped sofa with recliners will be the perfect spot to relax with a movie. If you have guests, they could sleep here or on the hide-a-bed sofa sleeper. The dual entry bath includes a shower with a seat for added comfort, and the front master bedroom will feel just like home with its king bed slide out and master closet. There is also a dresser and stackable washer and dryer prep if you want to add those appliances!

With any Keystone luxury Alpine Avalanche Edition fifth wheel, you will experience wide-body construction that allows you to stretch out and stay awhile during any season thanks to the Polar Pack All Season Protection that includes a heated and enclosed underbelly, an Astro foil reflective layer on the roof, front and rear walls, and two static attic vents, plus more! The interior offers hardwood slide out fascia with wood accents, crown molding, plus your choice of modern interior design. There are many more Keystone exclusives, like the Tru-Fit slide construction, the in-floor heating ducts, KeyTV™, and much more to bring you a full-packed, luxury fifth wheel!
