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.

This floorplan carries its water comfortably. A full 54-gallon fresh tank is roughly 25% of the 1,785-pound cargo capacity, leaving the 30RKD with a usable gear budget even when you tow full.

The published dry tongue weight of 955 pounds is 12% of the 7,715-pound dry weight, which sits inside the 10–15% band usually quoted for stable towing. It is still a dry figure: loading the front pass-through and the fresh tank both push it up.

Tank balance is generous here: 54 gallons of fresh against 60 grey and 30 black, so waste capacity keeps pace with supply and the fresh tank is the constraint that ends a dry stay.

Ranked by dry weight, the 30RKD sits 3 of 8 in the Cougar line: 7,715 pounds against a line that runs from 6,640 to 11,625 pounds. That position is the useful thing to know, because the plans immediately either side of it are the real alternatives.

Either side of it in the same line: Cougar 28BHS is 325 pounds lighter at 7,390 lb dry; and Cougar 23MLE is 30 pounds heavier at 7,745 lb dry.

Against the 30RKD: the Longitude 310RL is 7 lb lighter and 1 ft longer; the Classic 30RB is 10 lb heavier and 3 ft shorter and sleeps 2 fewer; the Voyage 3033BH is 11 lb heavier and sleeps 1 more. 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 travel trailers 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 15 of them for the 30RKD. 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: GVWR, 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 (92%) 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.
