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, drawers, 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 with storage drawers. There is also a pivoting entertainment door with a hidden pantry and cordless vacuum prep behind; how convenient!

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 hardwood cabinet doors, solid surface kitchen countertops, an Oxygenics shower head and hose, plus a Vent-All window system. You will also appreciate the 12V charging stations throughout, the dual zone Bluetooth audio system, and the on-demand water heater for added comfort. The exterior is also fully outfitted with a convenience center, MaxTurn technology, Lippert axles with anti-lock braking system, and a Curt Road Armor shock absorbing equalizer for smooth towing. Each model is available with the optional Hero Edition. By choosing this edition, you can help support our nation's heros and their families by contributing to the Wounded Warrior Project. This optional package features an industry exclusive full-body paint matte finish, frameless windows, a glass entry door, blackout rims, and green LED exterior accent lighting; see dealer for more details!
