Description

Keystone Cougar fifth wheel 360MBI highlights:

Middle Den/Bonus Room
Loft Area
Kitchen Island
Theater Seating
Pivoting Entertainment Door

You'll love having an extra room that you can decide what to do with on this Cougar fifth wheel! There is a tri-fold sleeper sofa here, a desk plus two wardrobes for storage. Above this room is a loft which adds more sleeping space without taking up precious interior living space. And speaking of space, you'll find more of it in the main living area when you push out the opposing slides. A second tri-fold sleeper sofa sits in the living area, and there is also theater seating that you can rest on in front of the entertainment center with a hidden pantry. The full bathroom has a linen closet for your towels and washcloths, and there is also great storage in the front private bedroom with the under-bed storage, dresser with a sliding top, and a full-height wardrobe. Outside, you'll find two power awnings, an unobstructed pass-thru storage, and an outdoor kitchen prep area!

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, shaker style 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 slam-latch baggage doors. 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!

Exceptional Customer Service
We can't say enough about the exceptional customer experience/service that the entire team at Mountaineer RV demonstrated as we navigated the purchase of a 2025 Keystone Cougar 5th Wheel Camper and installation of a BW Hitch. In addition, we ran into an issue with our trade-in, luckily the owner, Gina

Sheila
Very Professional
Was traveling from out of state thru that area. Had issue and needed parts to get me back home 12 hours away. Can’t remember young man at parts counter name (sorry). Was very professional in every way. Please recognize him for his outstanding customer service

Gene
We would highly recommend this dealer
My husband and I decided to travel two hours to Mountaineer RV in Jane Lew for our first camper and we are so glad we did! All of the staff are incredibly kind and helpful! They don't rush or pressure you. The whole process was so smooth and simple. They even did a walk through of the camper with us
