New 2026 Keystone RV Cougar 360MBI Fifth Wheel

2026 Keystone Cougar 360MBI

Available to Order

This 2026 Keystone Cougar 360MBI 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 Cougar fifth wheel with a middle den, loft area, kitchen island, and a flexible layout for family, guests, or extended stays.

The middle den is the main advantage of this floorplan. It gives you a separate bonus room with a tri-fold sleeper sofa, desk, and two wardrobes, so the space can work as a bunk room, guest room, office, or private hangout area. That flexibility makes this layout more useful than a standard rear living fifth wheel for families or buyers who need extra space.

The loft above the den adds another sleeping area without taking up floor space in the main living room. This is a practical feature for kids, guests, or extra storage when you are camping for longer periods.

The main living area uses opposing slides to open up the space around the theater seating, second tri-fold sleeper sofa, kitchen island, and entertainment center. The pivoting entertainment door also hides a pantry behind it, giving you more food storage while keeping the living area clean and organized.

The kitchen island adds prep space and makes the kitchen easier to use for regular meals. The full bath includes a linen closet for towels and supplies, while the front private bedroom gives the owners under-bed storage, a dresser with sliding-top hidden storage, and a full-height wardrobe.

Outside, the two power awnings, unobstructed pass-through storage, and outdoor kitchen prep area help make the campsite more usable.

Key features include a middle den, loft area, kitchen island, theater seating, pivoting entertainment door, hidden pantry, opposing slides, two tri-fold sleeper sofas, desk, two den wardrobes, front private bedroom, under-bed storage, dresser with hidden storage, full-height wardrobe, full bath, linen closet, two power awnings, unobstructed pass-through storage, outdoor kitchen prep area, 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.

For buyers looking for a Cougar fifth wheel they can order with a bonus room, loft sleeping space, and a wide-open living area, this 2026 Keystone Cougar 360MBI gives you the flexibility, storage, and comfort needed for longer trips or family camping.
