Ready to hit the road in style? The 2016 Keystone Cougar 333MKS is a premium, triple-slide fifth wheel built for travelers who refuse to leave comfort behind. Stretching nearly 38 feet, this extended-stay champion blends residential luxury with rugged towability, making it the ultimate home on wheels for weekend getaways or cross-country adventures.
The Ultimate Open-Concept Living Space: Step inside and experience a layout that feels less like a camper and more like a high-end apartment. The innovative triple-slide design blows the living and kitchen areas wide open, creating an expansive, airy atmosphere. At the heart of it all is a gourmet kitchen island with beautiful solid-surface countertops, dual sinks, a premium microwave and three-burner range, and a beautiful wood-paneled refrigerator that blends seamlessly into the cabinetry. Whether you are whipping up a quick breakfast or hosting a dinner party at the campsite, this kitchen delivers the space and style you need.
Four-Season Ready and Built Tough: The Cougar 333MKS is not just a fair-weather trailer. Thanks to Keystone's famous Polar Package, you get a fully enclosed, forced-air heated underbelly. This freeze-proof design keeps you comfortable from early spring chills to late autumn freezes. On the outside, the high-gloss fiberglass finish, aerodynamic front cap for easier towing, and an electric awning with integrated LED lighting ensure you look good wherever you set up camp. This premium look is elevated by sleek, automotive-style frameless windows, which protect the seals from heavy weather and allow you to keep them tilted open for fresh airflow even during a steady downpour.
