2027 Keystone Cougar Half-Ton22MLS

Keystone publishes three weights for the Cougar Half-Ton 22MLS: a shipping weight of 6,335 lb, a carrying capacity of 1,565 lb and a hitch weight of 700 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, 40 gal gray and 40 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.

Against the 11 Cougar Half-Ton floorplans profiled here, this one is the 2nd 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 22MLS. 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 22MLS differs from the other six Cougar Half-Ton travel trailers. Most distinctive first. Each rank counts only the siblings that publish that field, and a figure most of them share is left out.

• Hitch weight as Keystone lists it, 700 lb: lightest of seven; next is the 21LBK (760 lb).
• Grey tank, 40 gal: smallest of seven; next are the 21LBK, 25FKD and four others (80 gal).
• Shipping weight (Keystone’s term), 6,335 lb: second-lightest of seven, between the 21LBK (6,090 lb) and the 25MLE (6,970 lb).
• Carrying capacity (Keystone’s term), 1,565 lb: second-smallest of seven, between the 25FKD (1,395 lb) and the 21LBK (1,910 lb).
• Length, 26 ft 5 in: second-shortest of seven, between the 21LBK (25 ft 11 in) and the 25FKD and 25MLE (29 ft 11 in).
• Hitch weight as a share of shipping weight, 11%: smallest of seven, level with the 29RKE; next is the 25MLE (12.1%).
• Sleeping capacity, 4: smallest of seven, level with the 21LBK; next are the 25FKD, 25MLE and three others (6).

Next to the 21LBK, the nearest lighter floorplan by shipping weight, the 22MLS is 245 lb heavier by shipping weight, has 345 lb less carrying capacity, has a hitch weight 60 lb lighter, is 6 in longer and has a grey tank 40 gal smaller; the two publish the same exterior height, fresh tank and sleeping capacity.

Next to the 25MLE, the nearest heavier floorplan by shipping weight, the 22MLS is 635 lb lighter by shipping weight, has 1,110 lb less carrying capacity, has a hitch weight 145 lb lighter, is 3 ft 6 in shorter, has a grey tank 40 gal smaller and sleeps two fewer; the two publish the same exterior height and fresh 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 21LBK, nearest on the published figures. It differs on 3 of the 5 fields both publish (this plan first): length 26 ft 5 in vs 25 ft 11 in; hitch weight 700 lb vs 760 lb; grey tank 40 gal vs 80 gal. They match on sleeps and fresh tank.
