2027 Keystone Montana High Country300RK

Keystone publishes three weights for the Montana High Country 300RK: a shipping weight of 12,540 lb, a carrying capacity of 3,160 lb and a hitch weight of 2,055 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 Montana High Country 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 77 gal fresh, 100 gal gray and 50 gal waste, as Keystone lists them. Fresh water weighs about 8.3 lb per US gallon, so a full fresh tank is roughly 639 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 3 Montana High Country floorplans profiled here, this one is the 2nd by Keystone’s shipping weight, in a range from 12,275 lb (290RL) to 15,865 lb (391TB). 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 23 Oct 2026 from Keystone’s own floorplan page for the Montana High Country 300RK. That page carries no model year, so the year comes from the roster page that links it, which lists the Montana High Country 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 300RK differs from the other eight Montana High Country floorplans. 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.

Keystone lists 5 Montana High Country floorplans for 2027. 3 have a complete Keystone figure set and no existing page here, and are profiled, from 12,275 lb to 15,865 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 Montana High Country 290RL, nearest on the published figures. It differs on 2 of the 5 fields both publish (this plan first): length 34 ft 11 in vs 33 ft 11 in; hitch weight 2,055 lb vs 2,255 lb. They match on sleeps, fresh tank and grey tank.
