Keystone Cougar fifth wheel 354FLS highlights: Separate Living Area Rear Bedroom Tri-Fold Sleeper Sofas Patent-Pending Windshield Pull-Out Storage Tray   This Cougar fifth wheel will make you feel like you're on top of the world! It offers you a living space that truly feels like home because of its residential layout. The front separate living room has all of your favorite features, like a fireplace, LED HDTV, two 68" tri-fold sleeper sofas, and theater seating. The kitchen is centrally located and sectioned off from the rest of the interior so that you don't have to try to cook on top of someone who is lounging in front of the TV. You can add an optional free-standing dinette to the slide out across from the kitchen for a place to sit down and eat those delicious meals, and the two entry doors give you access to the front or back portion of this unit. The rear private bedroom has a queen-size bed with a shoe garage underneath, and there is a wardrobe slide that can be used for other clothing items.    Spend more time having fun and less time worrying about your RV with the Keystone Cougar fifth wheel! These units have all that you will need for excellent vacations. The interior comes with 5/8" one-piece DynaSpan® flooring, tall slide outs for added comfort and head room, night roller shades throughout, and residential, raised-panel hardwood cabinet doors and drawers. You will also enjoy decorative crown molding, a 5,500 BTU electric fireplace with thermostat control and remote, and a Max Air exhaust fan with rain sensor. The exterior is also fully outfitted with a convenience center, friction-hinge entry door, electric four-point auto leveling system, and Lippert SolidStep® on the main entry. There is a full pass-through storage with slam-latch baggage doors, an industry-best 80-gallon fresh tank capacity, a 2" accessory hitch with 300-LB storage capacity, and an outside shower.
