01 What the Cougar line is
Keystone's Cougar is among the longest-running and best-selling towable RV nameplates in North America, and over the years it has grown into two distinct families that share a name and a build philosophy but target different trucks. Understanding the split is the key to shopping the line.
The full-size Cougar is the flagship: a fifth-wheel-only family of heavier, more residential coaches running roughly 30 to 40 feet, riding on 5,100-pound axles with H-rated 16-ply tires, standing about 13′4″ tall, and carrying a 16-cubic-foot residential refrigerator, 75-gallon fresh water and 50-amp service. These are coaches for buyers with a three-quarter-ton or one-ton truck who want a true four-season home on wheels. The Cougar Half-Ton family is engineered around a different constraint — being towable by a properly equipped half-ton truck — with lighter 4,400-pound axles, Goodyear Endurance E-rated tires, smaller tanks and lower pin or tongue weights. Critically, Keystone offers the Half-Ton in both tow configurations: as a fifth wheel (raised front bedroom, more stable tow, needs a truck bed) and as a travel trailer (bumper-pull, no bed required, lower entry price).
Construction is consistent and central to the pitch across all three: a five-sided aluminum superstructure, laminated HyperCore composite sidewalls, HyperDeck water-resistant flooring on the travel trailers, a fully walkable one-piece TPO roof under a lifetime limited roofing warranty, and a forced-air heated, enclosed underbelly under the Climate Guard package — tested and approved from 0 to 110 degrees Fahrenheit, with 12-volt heat pads on the holding tanks. The line ships with auto-leveling on the fifth wheels, a tankless on-demand water heater, an automotive-grade painted fiberglass front cap and a Winegard 360+ antenna. Keystone backs the trailers with a one-year base warranty and an available three-year structural warranty.
02 Floorplans profiled in depth
Eight representative floorplans across all three product types — full-size Cougar fifth wheels, Cougar Half-Ton fifth wheels and Cougar Half-Ton travel trailers — are profiled in full with factory- and RVUSA-verified specifications, spanning rear-living couples, rear-kitchen, double-bunk family and two-bedroom flagship layouts, with deliberate fifth-wheel-versus-travel-trailer cross-shop pairs built in. The remaining Cougar and Cougar Half-Ton floorplans are catalogued for reference and will be profiled as the catalog expands.
| Floorplan | Family | Type | Dry wt | Length | Sleeps | Layout | MSRP |
|---|---|---|---|---|---|---|---|
| 25RDS | Half-Ton | TT | ~6,640 lbs* | 29' 10" | 6 | Rear-living couples, dual entry | $51,555 |
| 28BHS | Half-Ton | TT | ~7,390 lbs* | 32' 11" | 10 | Double-bunk family, outside kitchen | $52,845 |
| 30RKD | Half-Ton | TT | 7,715 lbs | 34' 9" | 6 | Rear-kitchen dual-slide couples | $57,375 |
| 23MLE | Half-Ton | 5W | 7,745 lbs | 27' 11" | 6 | Shortest half-ton 5W, mid-living | $59,985 |
| 26RKE | Half-Ton | 5W | 9,200 lbs | 30' 10" | 6 | Rear-kitchen dual-slide 5W | $68,078 |
| 29BHL | Half-Ton | 5W | 8,345 lbs | 33' 4" | 10 | Bunkhouse 5W, best HT payload | $66,510 |
| 316RLS | Cougar | 5W | 10,792 lbs | 35' 8" | 6 | Iconic rear-living triple-slide | $83,318 |
| 364BHL | Cougar | 5W | 11,625 lbs | 39' 0" | 10 | Two-bedroom 1.5-bath flagship | $86,430 |
Weights for the full-size Cougar (316RLS, 364BHL) and the Cougar Half-Ton fifth wheels (23MLE, 26RKE, 29BHL) are factory figures from the 2026 Keystone brochures, with GVWR derived as shipping weight plus carrying capacity per Keystone's own definition. For the half-ton travel trailers, payload, hitch weight, dimensions and tanks are RVUSA-verified; dry weight is the Keystone factory floorplan figure where the current dimensions match (30RKD, 25RDS) and dealer-typical and flagged (*) where not factory-published for 2026 (28BHS). Keystone notes brochure weights are pre-production estimates, and real loaded tongue or pin weights run higher — always confirm against the unit's own weight sticker and your truck's payload.
03 The two families compared
The single most useful thing to understand before shopping the Cougar line is how the full-size Cougar and the Cougar Half-Ton differ — and, within the Half-Ton, how the fifth-wheel and travel-trailer versions compare. The table below lays out the engineering differences that drive the choice.
| Attribute | Cougar (full-size 5W) | Cougar Half-Ton 5W | Cougar Half-Ton TT |
|---|---|---|---|
| Tow type | Fifth wheel | Fifth wheel | Travel trailer |
| Target truck | ¾-ton / 1-ton | Half-ton (equipped) | Half-ton (equipped) |
| Axles | 2 · 5,100 lb | 2 · 4,400 lb | 2 · 4,400 lb |
| Tires | H-rated 16-ply | Goodyear Endurance E | Goodyear Endurance E |
| Height (approx) | 13' 4" | 12' 7" | 11' 5" |
| Fresh / grey / black | 75 / 76 / 38 gal | 54 / 60 / 30 gal | 54 / 60 / 30 gal |
| Refrigerator | 16 cu ft 12V | 12V | 10 cu ft 12V |
| Hitch load | Pin (in-bed) | Pin (in-bed) | Tongue (bumper-pull) |
| Profiled dry range | 10,792-11,625 lbs | 7,745-9,200 lbs | ~6,640-7,715 lbs |
A fifth wheel carries its hitch load (the pin weight) on a hitch mounted in the truck bed, over the rear axle, which makes for a more planted, less sway-prone tow and frees the main floor with a raised front bedroom — but it requires a pickup with an open bed. A travel trailer tows from a bumper-pull hitch behind the vehicle, needs no truck bed and costs less to enter, but tows less stably and lands its tongue weight behind the rear axle. For a deeper treatment of the trade-off, see the travel trailer vs. fifth wheel guide.
04 Family & model-year notes
Two families, three product types — shop the split first
"Cougar" covers both the full-size flagship fifth wheel and the half-ton-towable Cougar Half-Ton, and the Half-Ton is sold as both a fifth wheel and a travel trailer. The three differ in axles, tires, height, tanks and hitch type. Decide your truck and tow type before comparing floorplans — a 364BHL and a 29BHL share a bunkhouse idea but ask for very different trucks.
Published weights are pre-production estimates
Keystone's brochures state plainly that listed weights and lengths are pre-production estimates. Owner-scaled real-world figures — tongue weight on the 25RDS travel trailer is a documented example — can run materially above the published dry hitch figure once water, gear and storage are loaded. Treat brochure pin and tongue weights as a floor, weigh the loaded trailer, and match it honestly to your truck's payload and rear-axle ratings.
Brochure vs. dealer-listed weights
For some plans the factory brochure pin weight differs slightly from the value in third-party listing databases (the full-size 316RLS, for instance, shows 1,900 lb in Keystone's brochure against a higher figure in some listings). These pages use the factory brochure as the primary source for the full-size Cougar and the Half-Ton fifth wheels, and RVUSA structured records for the half-ton travel trailers' payload and tongue weight.
Four-season build is a genuine differentiator
The Climate Guard package — a forced-air heated, enclosed underbelly with 12-volt tank heat pads, tested 0 to 110 degrees — together with HyperCore composite walls and a walkable one-piece roof is central to Cougar's positioning against lighter-built competitors. The construction figures on these pages follow Keystone's published specifications.

Coverage is not complete, and this matters. These campaigns come from two passes over NHTSA’s public record: a query-by-query harvest of the recall API (1,556 queries, of which 0 failed and 242 returned an explicit zero), and a sweep of NHTSA’s complete recall flat file (325,650 rows), which added 46 campaigns the API harvest had missed. It missed them because the roster it worked from was built by a catalog endpoint that refuses most requests, so entire manufacturer names were never asked about — NHTSA files several Forest River sub-brands as makes of their own. Two limits remain: NHTSA sometimes files a roster under a parent name, and some matches below rest on the wording of the recall rather than its model field. Campaigns affecting only pre-2005 units fall outside this catalog’s range and are not listed. This page is a starting point, not a clearance. Check a specific VIN at NHTSA before you buy, and again before you tow.

How this count is drawn. A report is counted here only when NHTSA’s own model field names this line. What the owner typed in the description is never used to attribute a report: our line names are ordinary English words, and an owner writing “imagine my surprise when the axle went” or naming the state of Montana is not reporting a Grand Design Imagine or a Keystone Montana. The total does include reports NHTSA filed under this line’s own trim badge — Cougar High Country — because it names the same trailer.
Read these as reports, not as findings. Complaints are submitted by owners and NHTSA does not verify them; no complaint here has been confirmed as a defect, and none of them is a recall. The sample is also self-selected — only owners motivated to file appear in it — so a high count tracks how many units a line sold at least as much as how well it was built. Use the pattern, not the total: a component that keeps recurring is worth inspecting on any used unit. File or search complaints at NHTSA.
