Description
2026 Keystone Cougar 350LLK
Available to Order
This 2026 Keystone Cougar 350LLK 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 rear luxury kitchen, four slide-outs, a middle living room, and a front private bedroom built for longer stays.
The rear luxury kitchen is the main advantage of this floorplan. It gives you wrap-around counter space, a large sink, dishwasher prep, solid surface countertops, and the appliance space needed for regular cooking. This is a strong layout for buyers who want a fifth wheel kitchen that feels more residential and easier to use than a standard center kitchen setup.
The middle living area gives everyone a comfortable place to gather. The L-shaped sofa, fireplace, TV, 12V ceiling fan, and dinette with bench seating and chairs create a main room that works well for meals, relaxing, movie nights, or spending time inside during bad weather.
The four-slide design helps open up the kitchen, living area, and bedroom, giving this Cougar a more spacious feel once it is set up. The full bath includes a shower with a seat, Oxygenics shower head, and a large vanity counter, giving you more room for daily use.
Up front, the private bedroom includes a queen bed slide-out, full-height wardrobe, pull-out laundry center, under-bed storage, and stackable washer/dryer prep. That setup gives the owners strong clothing storage and better long-stay convenience.
Key features include rear luxury kitchen, four slide-outs, queen bed slide-out, front private bedroom, wrap-around kitchen counter space, large sink, dishwasher prep, solid surface countertops, middle living room, L-shaped sofa, fireplace, TV, 12V ceiling fan, dinette with bench seating and chairs, full bath, shower with a seat, large vanity counter, full-height wardrobe, pull-out laundry center, under-bed storage, washer/dryer prep, hardwood cabinet doors, 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.
For buyers looking for a Cougar fifth wheel they can order with a true residential-style kitchen, comfortable living space, and strong bedroom storage, this 2026 Keystone Cougar 350LLK gives you the space and features that make extended weekends and longer stays easier.
