2027 Keystone Cougar320RDS

Keystone publishes three weights for the Cougar 320RDS: a shipping weight of 11,283 lb, a carrying capacity of 2,467 lb and a hitch weight of 1,775 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 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 75 gal fresh, 76 gal gray and 38 gal waste, as Keystone lists them. Fresh water weighs about 8.3 lb per US gallon, so a full fresh tank is roughly 622 lb on the road before anything else is loaded. The tire size Keystone lists is ST235/80R16H; 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 7 Cougar floorplans profiled here, this one is the 4th by Keystone’s shipping weight, in a range from 9,674 lb (260MLE) to 12,499 lb (360MBI). 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 320RDS. That page carries no model year, so the year comes from the roster page that links it, which lists the Cougar 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 320RDS differs from the other eleven Cougar 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. Not every one of these pages covers the same model years as this one (2027); each figure is the one its own page prints, so a rank compares pages, not one model year.

Next to the 316RLS (2026 page), the nearest lighter floorplan by shipping weight, the 320RDS is 491 lb heavier by shipping weight, has 359 lb more carrying capacity, has a hitch weight 125 lb lighter and is 1 ft 2 in longer; the two publish the same exterior height, fresh tank, grey tank and sleeping capacity.

Next to the 364BHL (2026 page), the nearest heavier floorplan by shipping weight, the 320RDS is 342 lb lighter by shipping weight, has 92 lb more carrying capacity, has a hitch weight 605 lb lighter, is 2 ft 2 in shorter and sleeps four fewer; the two publish the same exterior height, fresh tank and grey tank.

Keystone lists 10 Cougar floorplans for 2027. 7 have a complete Keystone figure set and no existing page here, and are profiled, from 9,674 lb to 12,499 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 316RLS, nearest on the published figures. It differs on 2 of the 5 fields both publish (this plan first): length 36 ft 10 in vs 35 ft 8 in; hitch weight 1,775 lb vs 1,900 lb. They match on sleeps, fresh tank and grey tank.
