You will be so excited to take this Cougar fifth wheel out for the first time! Because of its secluded and fully stocked master suite at the front, this unit is perfect for a couple who wants to see the country or visit family. The master bathroom has a wonderful walk-in closet that has shoe storage and preparations for a washer/dryer. There is also under-bed storage in the bedroom portion, and the queen bed slide gives you a little more space to get to the dresser and linen closet. The half bathroom is located out in the main living area so that your friends will have a place to go when they visit. Opposing slides keep this living area open for lounging comfortably on the tri-fold sleeper sofa and theater seating, and you can get everyone together for a board game at the booth dinette. 

 

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 LCI® 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.
