2026 Keystone Cougar 355FBS
Available to Order
This 2026 Keystone Cougar 355FBS is available to order through Barton Lake RV. Availability, colors, equipment, and final pricing may vary, but this floorplan is a strong fit for buyers who want a larger Cougar fifth wheel with a true front master suite, bath and a half layout, kitchen island, and open rear living space.
The front master suite is one of the biggest advantages of this floorplan. The bedroom includes a queen bed slide-out, under-bed storage, dresser, linen closet, and direct access to the master bathroom. This gives the owners a more private and comfortable setup for longer trips or extended stays.
The master bathroom adds a major residential-style benefit with a walk-in closet, shoe storage, drawers, and washer/dryer prep. Having this much storage in the front suite makes the camper much easier to live out of for more than just a weekend.
The main living area uses opposing slides to open up the space around the tri-fold sleeper sofa, theater seating, booth dinette with storage drawers, fireplace, and kitchen island. The pivoting entertainment door with hidden pantry storage keeps the living area clean while adding practical food storage behind the entertainment center.
The half bath is another strong feature, especially when guests are visiting or sleeping in the main living area. It gives everyone bathroom access without having to go through the private master suite.
Outside, the two power awnings give you more covered campsite space, making it easier to relax, cook, or spend time outdoors.
Key features include a bath and a half layout, front master suite, queen bed slide-out, master bathroom, walk-in closet, shoe storage, dresser, linen closet, under-bed storage, washer/dryer prep, kitchen island, opposing slides, tri-fold sleeper sofa, theater seating, booth dinette with storage drawers, fireplace, 12V ceiling fan, pivoting entertainment door, hidden pantry, cordless vacuum prep, two power awnings, hardwood cabinet doors, solid surface kitchen countertops, Oxygenics shower head, Vent-All window system, 12V charging stations, dual-zone Bluetooth audio, on-demand water heater, convenience center, MaxTurn technology, Lippert axles with anti-lock braking system, and Curt Road Armor shock-absorbing equalizer.
