2026 Cougar Half-Ton30RKD

The Cougar Half-Ton 30RKD is built for couples who cook. The rear of the coach is a full kitchen — counter space, a large sink and storage spread across the back wall under a bank of windows — rather than the more common rear lounge or rear bath. A front king bedroom gives the sleeping space privacy, and two opposing slides open the mid-coach living and dining area into something that feels far larger than a single-slide trailer. It sleeps six nominally, but like the rest of the rear-kitchen plans it is fundamentally a two-person coach with room for occasional guests.

It carries the 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 package. Tandem 4,400-pound axles ride on Goodyear Endurance E-rated tires, and a 10-cubic-foot 12-volt Norcold refrigerator, a tankless water heater and 50-amp service equip it for extended stays.

The 30RKD is the heaviest travel trailer profiled in the Cougar Half-Ton line here — at 7,715 pounds dry against its chassis rating it leaves 1,785 pounds of payload, the tightest cargo margin of the three travel trailers, so it rewards careful loading and a truck with payload to spare. Its dry weight is the Keystone factory floorplan figure for the current layout, and the 955-pound tongue weight is a pre-production estimate that will rise loaded. For two travelers who want a genuine rear kitchen and the openness of dual slides without stepping up to a fifth wheel, the 30RKD is the most residential travel trailer the Cougar Half-Ton line offers.

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 30RKD 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.

A full 54-gallon fresh tank is about 450 lb of water, 25% of the 30RKD’s 1,785 lb cargo capacity, leaving 1,335 lb (222 lb per rated berth). Across 3 Cougar travel-trailer floorplans the water share runs 18% to 25%, and this plan’s is the highest. Nearest on that share: Cougar 25RDS at 20%.

Closest sibling: the Cougar 25RDS, nearest on the published figures. It differs on 4 of the 8 fields both publish (this plan first): length 34 ft 9 in vs 29 ft 10 in; dry weight 7,715 lb vs 6,640 lb; cargo capacity 1,785 lb vs 2,293 lb; dry hitch weight 955 lb vs 885 lb. They match on sleeps, fresh tank, grey tank and black tank.

Either side of it by dry weight: Cougar 28BHS is 325 lb lighter (7,390 lb dry).
