2027 Keystone Cougar Half-Ton26RES

Keystone publishes three weights for the Cougar Half-Ton 26RES: a shipping weight of 8,240 lb, a carrying capacity of 2,060 lb and a hitch weight of 1,540 lb. Those are Keystone’s own terms, and this page keeps them. Keystone does not call the first figure dry or unloaded weight, does not say the hitch figure is measured dry, and publishes no GVWR for any Cougar Half-Ton floorplan, so none of the three is renamed here and no loaded rating is worked out from them. The trailer’s own federal weight label, inside the door, is the document that carries its UVW, cargo capacity and GVWR.

Tank capacities are 54 gal fresh, 60 gal gray and 30 gal waste, as Keystone lists them. Fresh water weighs about 8.3 lb per US gallon, so a full fresh tank is roughly 448 lb on the road before anything else is loaded. The tire size Keystone lists is ST225/75R15E; a fifth wheel puts its pin load into the truck bed, so it counts against the truck’s payload rather than its tow rating.

Against the 11 Cougar Half-Ton floorplans profiled here, this one is the 6th by Keystone’s shipping weight, in a range from 6,090 lb (21LBK) to 9,590 lb (30REP). Every figure in that comparison comes from the same Keystone page type for the same model year, so the comparison inside the series is like for like.

Every number on this page was read on 19 Oct 2026 from Keystone’s own floorplan page for the Cougar Half-Ton 26RES. That page carries no model year, so the year comes from the roster page that links it, which lists the Cougar Half-Ton floorplans under the heading “2027 Floorplans”. Keystone notes that its website reflects the most recent production run and that features and specifications change during the year.

How the 26RES differs from the other three Cougar Half-Ton fifth wheels. Most distinctive first. Each rank counts only the siblings that publish that field, and a figure most of them share is left out.

• Shipping weight (Keystone’s term), 8,240 lb: lightest of four; next is the 28RLI (9,179 lb).
• Length, 30 ft 11 in: shortest of four; next is the 28RLI (32 ft 8 in).
• Exterior height, 12 ft 7 in: lowest of four; next are the 28RLI, 29MBD and 30REP (12 ft 8 in).
• Carrying capacity (Keystone’s term), 2,060 lb: second-smallest of four, between the 28RLI (1,821 lb) and the 29MBD (2,175 lb).
• Hitch weight as Keystone lists it, 1,540 lb: second-lightest of four, between the 28RLI (1,435 lb) and the 29MBD (1,635 lb).
• Hitch weight as a share of shipping weight, 18.7%: second-largest of four, between the 29MBD (17.5%) and the 30REP (19.7%).
• Sleeping capacity, 4: smallest of four, level with the 30REP; next is the 28RLI (6).

Next to the 28RLI, the nearest heavier floorplan by shipping weight, the 26RES is 939 lb lighter by shipping weight, has 239 lb more carrying capacity, has a hitch weight 105 lb heavier, is 1 ft 9 in shorter, stands 1 in lower and sleeps two fewer; the two publish the same fresh tank and grey tank.

Keystone lists 15 Cougar Half-Ton floorplans for 2027. 11 have a complete Keystone figure set and no existing page here, and are profiled, from 6,090 lb to 9,590 lb shipping weight; the others are catalogued on this page with the reason against each. Keystone publishes shipping weight, carrying capacity and hitch weight for these trailers, and no GVWR.

Closest sibling: the Cougar Half-Ton 30REP, nearest on the published figures. It differs on 2 of the 5 fields both publish (this plan first): length 30 ft 11 in vs 34 ft 11 in; hitch weight 1,540 lb vs 1,890 lb. They match on sleeps, fresh tank and grey tank.
