Forest River Rockwood Ultra Lite 2891BH vs Keystone Cougar 368MBI

Forest River Rockwood Ultra Lite 2891BH

• ✓Lightweight design can be towed by properly equipped half-ton trucks
• ✓Bunkhouse layout gives families space in a fifth wheel format
• ✓Outdoor kitchen keeps the cooking outside where it belongs

Keystone Cougar 368MBI

• ✓Mid-bunk room gives kids their own separate space with a door
• ✓Large holding tanks support week-long dry camping stays
• ✓Triple slides and 40 feet of space feel like a small home

Forest River Rockwood Ultra Lite 2891BH

• ✓Big U-shaped dinette in the slide doubles as extra sleeping and a great game/meal space — owners use it constantly
• ✓Better-than-expected kitchen: larger-than-typical microwave, a 22-inch oven, 11 cu ft fridge, a pantry, plus an outside kitchen with griddle
• ✓Solid construction for the tier — painted fiberglass front cap with clear coat, one-piece walkable laminated roof, aluminum truss bracing, six-sided aluminum frame
• ✓Dual-entry bathroom with the wardrobe slide is a smart, livable touch that bigger rigs often skip
• ✓Active Forest River owner forums make parts, mods, and troubleshooting easy
• ✓Strong value — a real bunkhouse fifth wheel for around $58K, undercutting comparable Grand Design and Keystone bunk models

• ✗The 'Ultra Lite half-ton towable' marketing is optimistic — forum consensus is that loaded pin weight pushes most owners to a 3/4-ton for real-world safety
• ✗A single A/C struggles in hot, muggy weather — owners say it can't keep up, and the bunkroom especially gets warm
• ✗Forest River build-quality consistency is variable; a careful PDI is essential because units vary unit to unit
• ✗Eight-person sleeping is tight in practice — fine for a family with kids, cramped for eight adults
• ✗Bunkhouse plus living slide layout means storage, while good, fills up fast with a full family's gear
• ✗Lighter build trades some insulation and beef versus heavier fifth wheels — it's a 3-season-leaning rig
• ✗As a volume Forest River product, warranty/dealer experiences are hit-or-miss depending on your dealer

Keystone Cougar 368MBI

• ✓The mid-bunk floorplan is the family star — a private mid-room plus a queen pull-out sofa that effectively creates a second bedroom, so two sets of kids or guests have their own space
• ✓Sleeps eight comfortably for a real family vacation rig without going full toy-hauler bulk
• ✓Owners praise the fireplace and the cozy, residential feel of the main living area
• ✓Cougar is a mature, popular line with a deep parts pipeline and an active Keystone owner forum for troubleshooting
• ✓Strong value for a large family fifth wheel at around $68K versus pricier Grand Design and Montana bunk models
• ✓Good kitchen and living space for hosting — the layout is built for togetherness, not just sleeping
• ✓Widely available used, so you can find them at attractive prices with the right inspection

• ✗Multiple A/C duct leaks reported between the ceiling and roof from how the ducting was installed at the factory
• ✗Bedroom slide can leak in the rain due to a seal-channel design that dumps water onto a flat trim piece that pools
• ✗Bathroom skylight leaks reported by owners
• ✗Floor flex over the heating ducts in the main living area — enough that the kitchen island can rock on some units
• ✗Keystone build quality and warranty experiences draw mixed-to-frustrated reviews on the owner forums
