01 What makes it unique

The Cougar 364BHL is the big-family flagship of the line — a two-bedroom, bath-and-a-half fifth wheel that keeps its overall length under 40 feet. A rear bunk room with its own half-bath functions as a second bedroom for the kids, a private front bedroom up in the raised nose adds a wardrobe slide for storage, and three slide-outs open the main living level between them. It sleeps ten, and an outside kitchen with a refrigerator and griddle, an automotive windshield bringing natural light into the nose, and oversized exterior storage under the rear bed make it a coach built for families who travel often and stay a while.

This is the heaviest coach in the Cougar line profiled here, and the build is full residential: a five-sided aluminum superstructure, laminated HyperCore composite sidewalls, a walkable one-piece TPO roof under a lifetime limited roofing warranty, and a heated, enclosed underbelly under the Climate Guard package tested 0 to 110 degrees. Tandem 5,100-pound axles ride on H-rated 16-ply tires, four-point auto-leveling handles setup, and the equipment matches: a 16-cubic-foot 12-volt refrigerator, a 33,000-BTU dual-A/C system, a tankless water heater and a 76-gallon black tank sized for a bath-and-a-half and a full family.

At 11,625 pounds dry against a 14,000-pound GVWR it leaves 2,375 pounds of payload, sized for a family's gear, and its 2,380-pound dry pin weight is the highest of any Cougar profiled here — it lands directly on the tow vehicle and rises loaded, so the 364BHL squarely needs a properly equipped three-quarter-ton or one-ton truck, with a one-ton the safer choice once loaded. At 13′4″ tall and nearly 40 feet long it asks for route, clearance and site-length planning. For families who want two real bedrooms, a bath and a half and an outside kitchen in a fifth wheel that still fits most sites under 40 feet, the 364BHL is the top of the Cougar family range.

03 The Cougar floorplan family

Keystone's Cougar splits into two families. The full-size Cougar is the heavier flagship fifth wheel — 5,100-pound axles, H-rated tires and roughly 13′4″ of height. The Cougar Half-Ton line is engineered to be towable by a properly equipped half-ton truck, and Keystone offers it as both a fifth wheel and a travel trailer — lighter 4,400-pound axles, Goodyear Endurance tires, and lower pin or tongue weights. The 364BHL on this page is highlighted; each other profiled plan links to its own page. The full Cougar catalogue runs to dozens of floorplans across both families; the highest-demand layouts are detailed here and the rest are catalogued on the line hub.

Every full-size Cougar fifth wheel carries a 5-sided aluminum superstructure, laminated HyperCore composite sidewalls, a walkable one-piece TPO roof under a lifetime limited roofing warranty, a heated and enclosed underbelly (Climate Guard, tested 0–110°F), 5,100-pound axles on H-rated 16-ply tires, a 16-cubic-foot 12-volt refrigerator, 50-amp service and four-point auto-leveling. Lengths, weights and equipment change with options and model year — always confirm against the unit's own weight sticker. Additional Cougar and Cougar Half-Ton floorplans are documented on the line hub.

04 What owners & reviewers report

Two real bedrooms and a bath-and-a-half under 40 feet

A rear bunk room with its own half-bath plus a private front bedroom — the 364BHL functions as a two-bedroom coach while staying under 40 feet overall.

Built for families who stay a while

An outside kitchen with refrigerator and griddle, an automotive windshield for natural light, oversized rear exterior storage and a 76-gallon black tank — equipment sized for a full family on long trips.

The highest pin weight in the line here — plan the truck

At 2,380 lb dry the pin weight is the highest of any Cougar profiled here, lands directly on the truck and rises loaded; the 364BHL needs a properly equipped 3/4-ton, with a one-ton the safer choice loaded. Match it to your truck's ratings.

Plan for length and height

At nearly 40 feet long and 13' 4" tall the 364BHL asks for route, clearance and campsite-length planning — confirm site maximums and travel routes before booking.

05 How it compares

↓ Step down
Cougar Half-Ton 29BHL

The bunkhouse half-ton fifth wheel that also sleeps ten — far lighter and pullable without a heavy truck, but a single bath and less space and finish.

↔ Same line
Cougar 316RLS

The rear-living couples' flagship — the same full-size build without the second bedroom, shorter and lighter for two travelers.

↔ Cross-shop
Grand Design Reflection 311BHS

A comparably-sized bunkhouse fifth wheel from Grand Design — a close cross-shop on size, worth comparing on layout, warranty and standard equipment.
