2026 Cougar364BHL

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.

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.

This floorplan carries its water comfortably. A full 75-gallon fresh tank is roughly 26% of the 2,375-pound cargo capacity, leaving the 364BHL with a usable gear budget even when you tow full.

The published dry pin weight of 2,380 pounds is 20% of this floorplan’s 11,625-pound dry weight. Fifth-wheel pin weight rides in the bed of the truck, so it comes off payload rather than off tow rating — and it rises with the trailer as you load it, not in proportion to what you put over the axles.

Nothing above changes the ceiling. Loaded to its 14,000-pound GVWR the 364BHL is towing 2,375 pounds more than its 11,625-pound dry figure, and that is the number your vehicle has to be rated for — not the brochure weight.

Tank balance is generous here: 75 gallons of fresh against 76 grey and 76 black, so waste capacity keeps pace with supply and the fresh tank is the constraint that ends a dry stay.

Of the 5 Cougar floorplans profiled here that publish a GVWR, the 364BHL carries the highest GVWR at 14,000 pounds. It is the top of the line by weight, which makes tow-vehicle capability the first thing to settle rather than the last.

Either side of it in the same line: Cougar 316RLS is 1,100 pounds lighter at 12,900 lb GVWR.

Against the 364BHL: the Eagle 370FB is 1 ft longer and sleeps 5 fewer; the Avenue 32RLS is 5 lb lighter and 4 ft shorter and sleeps 6 fewer; the Model Z 2670 is 5 lb lighter and 9 ft shorter and sleeps 3 fewer. Those are differences in the published numbers only — what they cost, how they are built and how they live are separate questions each of those pages answers on its own terms.

Those are the nearest fifth wheels from other lines by weight — one per line, picked by proximity on that figure and nothing else. They are listed so the same tow vehicle can be checked against real alternatives, not because they are equivalent inside; layout, build and price diverge sharply across that group.

For scale, the Cougar floorplans profiled here run 6,640 to 11,625 pounds dry and 28 to 39 feet of exterior length across 8 plans. Where a floorplan falls in that spread usually says more about which vehicle can tow it, and which site it fits, than the layout name does.

Every profiled floorplan in this line, with the full weight table, is on the Cougar line hub.

This catalog tracks 18 specification fields per floorplan. Named sources publish 16 of them for the 364BHL. The rest are not shown, because the alternative is reading a figure across from a sibling floorplan or from what the segment usually does — and a number nobody published is worth less than an admitted gap.

Not published for this floorplan: exterior width, interior height, tire size (a tire description is published, a size is not). If you find one of these in a manufacturer document for this plan, it belongs on this page.

The completeness figure at the foot of this page (99%) measures the same thing on the full field set: it is a measurement of how much this floorplan’s manufacturer publishes, not of how much research went into the page.

How every figure here was sourced and checked is set out on the methodology page.
