A full rear bathroom creates a master suite in this fifth wheel! The private bedroom has a king bed slide with storage underneath for extra blankets, a chest with a TV, and access to the full bathroom which has a dual sink vanity, a shower with a seat, and a closet with stackable washer and dryer prep. The half bathroom is by the kitchen so you can quickly get back to preparing your delicious meal with the three burner cooktop and kitchen island then enjoy your meals at the free standing dinette. The front living area has a front entertainment center with a 40" fireplace and 50" TV with overhead cabinets to store your movies, as well as opposing tri-fold sofa sleeper slides and Thomas Payne theater seating with heat, massage, LED lights, and a USB charging station.

 

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!

What Our Customers Are Saying

I will not shop anywhere else for our next camper!

We purchased a camper from a private party and were looking to get setup for the 4th of July. The service department was able to take time and go over the ins and out of my new to me camper and also install a solar charging system. I can’t Express how grateful I am and when it comes time… I will not shop anywhere else for our next camper!!! - Thomas
