01 What makes it unique
The Cougar Half-Ton 25RDS is built around a layout couples ask for again and again: a real private front bedroom and a rear living room, in a travel trailer a half-ton truck can pull. A king bed sits in a walk-around front bedroom with its own exterior entry door, the rear of the coach is given over to a lounge with theater seating and a fireplace, and a walk-through bath connects the two with dual entry doors. It sleeps six on paper — a tri-fold sleeper sofa and the dinette handle guests — but this is fundamentally a two-person coach that spends its 30 feet on living space rather than bunks.
It carries Keystone's full Cougar Half-Ton build: a five-sided aluminum superstructure, laminated HyperCore composite sidewalls, HyperDeck water-resistant flooring, a walkable TPO roof under a lifetime limited roofing warranty, and a forced-air heated, enclosed underbelly under the Climate Guard four-season package. Tandem 4,400-pound axles ride on Goodyear Endurance E-rated tires, and the drop-frame chassis opens a large front pass-through. A 10-cubic-foot 12-volt Norcold refrigerator, a tankless water heater and a 50-amp service round out a well-equipped lightweight trailer.
A tow caution worth stating plainly: Keystone publishes an 885-pound dry tongue weight, but that figure is a pre-production estimate for an empty trailer. Owners who have put loaded 25RDS trailers on a scale have reported tongue weights well above that — in some cases past 1,200–1,300 pounds once water, gear and the pass-through are loaded, enough to exceed the rated payload of a typical half-ton once passengers are aboard. The 2,293-pound payload is generous for a couples' trailer, but weigh it loaded and match it to your truck honestly before relying on the brochure number. For couples who want a private bedroom and a rear lounge without a heavy truck, the 25RDS is one of the segment's default picks — bought with eyes open on real tongue weight.

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 25RDS 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.
| Floorplan | Family | Type | Nominal | Sleeps | Notable |
|---|---|---|---|---|---|
| 25RDS | Half-Ton | TT | 30 ft | 6 | Rear-living couples, dual entry, fireplace |
| 28BHS | Half-Ton | TT | 33 ft | 10 | Double-bunk family, outside kitchen |
| 30RKD | Half-Ton | TT | 35 ft | 6 | Rear-kitchen dual-slide couples |
| 23MLE | Half-Ton | 5W | 28 ft | 6 | Shortest half-ton fifth wheel, mid-living |
| 26RKE | Half-Ton | 5W | 31 ft | 6 | Rear-kitchen dual-slide half-ton 5W |
| 29BHL | Half-Ton | 5W | 33 ft | 10 | Bunkhouse half-ton 5W, sleeps 10 |
| 316RLS | Cougar | 5W | 36 ft | 6 | Iconic rear-living triple-slide flagship |
| 364BHL | Cougar | 5W | 39 ft | 10 | Two-bedroom 1.5-bath family flagship |
Every Cougar Half-Ton travel trailer carries a 5-sided aluminum superstructure, laminated HyperCore composite sidewalls and HyperDeck water-resistant flooring, a walkable TPO roof under a lifetime limited roofing warranty, a forced-air heated and enclosed underbelly (Climate Guard), 4,400-pound axles on Goodyear Endurance E-rated tires, a 10-cubic-foot 12-volt Norcold refrigerator and a tankless water heater. Lengths, weights and equipment change with options and model year — always confirm against the unit's own weight sticker. Additional Cougar floorplans are documented on the line hub.
04 What owners & reviewers report
A private bedroom and a rear lounge without a heavy truck
A walk-around king bedroom up front and a rear living room with theater seating and a fireplace, in a 30-foot trailer a half-ton can tow — the core appeal of the 25RDS.
Dual entry and a walk-through bath
Two entry doors and a center bath make the private bedroom genuinely private and the rear lounge its own space — a layout that lives larger than its length.
Verify real tongue weight before you tow
Keystone's published 885-lb tongue weight is a pre-production dry estimate; owners have scaled loaded 25RDS trailers well above it, in cases past 1,200–1,300 lb. Weigh the loaded trailer and check it against your truck's payload before relying on the brochure figure.
Dry weight is a factory estimate
The ~6,640-lb dry figure is the Keystone factory floorplan weight for the current layout; payload and tongue weight are RVUSA-verified. Confirm against the unit's weight sticker.
05 How it compares
The double-bunk family travel trailer — sleeps up to ten with an outside kitchen, heavier and longer for families rather than couples.
The shortest Cougar Half-Ton fifth wheel — a more stable tow and a drop-down bedroom, but needs a truck bed and a fifth-wheel hitch.
Forest River's rear-living couples' coach — lighter and with standard solar, but less four-season insulation and a smaller fridge.
