KeystoneMontana

Montana is Keystone's flagship fifth wheel and, by unit volume, the best-selling luxury fifth wheel in North America. It sits at the top of Keystone's towable ladder — above the Coleman value trailers, the Passport and Cougar mid lines, and the half-ton fifth wheels — in full-size, residential fifth-wheel territory aimed at full-timers and serious travelers with a three-quarter-ton or larger truck.

The pitch is residential-grade construction and four-season capability. Every Montana is built on a 12-inch I-beam chassis with z-frame technology, wrapped in 2-inch laminated fiberglass sidewalls over a double-laminated, insulated rear wall, and topped with a fully walkable Alpha seamless TPO roof on 5-inch rafters. The Four-Season Living package — a heated, enclosed underbelly with forced hot air and electric tank heaters, zero-degree tested — is standard, as is a MaxTurn fiberglass front cap in KeyShield automotive-grade paint, a Lippert hydraulic auto-leveling system, 50-amp service, hardwood cabinetry, solid-surface countertops and the La-Z-Boy furniture package. Keystone Exclusives like KeyTV source control, the Blade Pure air purifier and integrated 4G-and-WiFi prep round out the standard build.

For 2026 the luxury Montana line spans fifteen floorplans from a 35-foot rear-living couples' coach to a 43-foot, two-full-bath family flagship, and Keystone has begun rolling out a redesigned, wider-bodied Montana for the model year. Below the luxury line sits the Montana High Country sub-line: lighter, lower in profile and more travel-friendly, built on the same brand DNA but engineered to tow more easily and catalogued separately further down this page.

Thirteen luxury floorplans are profiled in full with RVUSA-verified specifications, covering nearly the entire 2026 line: the new widebody rear-living hero, the rear-living entry plan, three more rear-living couples' layouts (a kitchen-island plan with dual pantries, a rear-entertainment plan with a glass-door pantry, and the only side-patio plan in the class), the best-selling four-slide rear-living plan and a bike-garage variant, a galley-forward plan that sleeps six, a front-living bath-and-a-half entertainer, two family bunkroom-and-loft layouts (one with two full baths), a rear-kitchen bath-and-a-half full-timer, and a front-office full-timer with an outside kitchen. The two remaining redesigned-widebody plans and the Montana High Country sub-line are catalogued below and will be profiled as the catalog expands.

The luxury Montana line runs to fifteen floorplans for 2026. Thirteen are now profiled above and link to full pages; the two remaining redesigned-widebody plans — the 3800FL front-living and 3900RK rear-kitchen — appear on Keystone's site as part of the widebody rollout and are catalogued at the foot of the table below, to be profiled once their structured specifications publish.

Below the luxury Montana sits the Montana High Country: a lighter, lower-profile fifth wheel built on the same brand identity but engineered to be more travel-friendly — reduced height and weight for easier towing and storage, while keeping the residential interior style, the four-season build and the hydraulic auto-leveling. It is the choice for a buyer who wants the Montana name and finish in a more manageable coach, or who tows with a lighter three-quarter-ton setup. The 2026 High Country roster is catalogued below; each plan will be profiled with RVUSA-verified specifications in a later pass.
