01 What Montana is
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 now profiled in full at its own line hub.
02 Floorplans profiled in depth
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 are catalogued below; the Montana High Country sub-line is now profiled in full at its own hub.
| Floorplan | Dry wt | Length | Sleeps | Layout | MSRP |
|---|---|---|---|---|---|
| 3123RL | 12,881 lbs | 35' 1" | 4 | Rear-living entry, kitchen island | $116,693 |
| 3100RL | 14,030* lbs | 35' 11" | 4 | New widebody, rear-living couples, triple A/C | $156,900 |
| 3231CK | 13,169 lbs | 37' 5" | 4 | Rear living, kitchen island + dual pantries | $121,013 |
| 3531RE | 13,345 lbs | 38' 7" | 4 | Rear entertainment, glass-door pantry | $122,378 |
| 3532SP | 14,405 lbs | 39' 2" | 4 | Side patio, king bed, theater seating | $125,878 |
| 3795FK | 14,030 lbs | 39' 11" | 6 | Front raised kitchen, rear full bath, triple A/C | $136,128 |
| 3623EB | 14,135 lbs | 40' 2" | 4 | Bike garage, four slides, rear living | $129,878 |
| 3857BR | 15,618 lbs | 40' 11" | 8 | Middle bunkroom + loft, family | $130,688 |
| 3761FL | 14,951 lbs | 41' 0" | 6 | Front living, bath-and-a-half, 5 slides | $130,433 |
| 3781RL | 14,290 lbs | 41' 0" | 4 | Best-selling rear living, kitchen island | $139,999 |
| 3901RK | 14,755 lbs | 42' 4" | 4 | Rear kitchen, bath-and-a-half, front master | $133,778 |
| 3941FO | 15,644 lbs | 42' 7" | 6 | Front office full-timer, outside kitchen | $137,153 |
| 3915TB | 15,222 lbs | 43' 0" | 6 | Two full baths, bunkroom + loft | $137,228 |
Body specifications (lengths, heights, payload, tanks, refrigerator, sleeping, slides and A/C) are RVUSA-verified against the 2026 structured spec records, each page fp-slug and title checked; pin (hitch) weights are from the same records or factory roster. GVWR is handled per plan: where a plan publishes both a base dry weight and a payload, the GVWR shown is their sum (3231CK, 3531RE, 3623EB); the 3901RK carries a directly published 18,000-pound GVWR. The lighter rear-living plans (3123RL, 3231CK, 3531RE, 3623EB) sit below the line's 18,000-pound full-timer rating. Three plans (3532SP, 3781RL, 3795FK) carry a 2026-verified dry weight but a flagged (*) GVWR and payload pending plan-specific factory publication, and the new widebody 3100RL has its dry weight and GVWR flagged. Real loaded pin weights run higher — weigh the loaded coach and confirm against your truck's payload and rear-axle ratings.
03 The full 2026 luxury lineup
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.
| Floorplan | Layout | Status |
|---|---|---|
| 3100RL | Widebody rear living, couples | Profiled |
| 3123RL | Rear living, kitchen island | Profiled |
| 3231CK | Rear living, kitchen island + dual pantries | Profiled |

| 3941FO | Front office full-timer, outside kitchen | Profiled |
| 3800FL | Front living, redesigned widebody | Catalogued |
| 3900RK | Rear kitchen, redesigned widebody | Catalogued |
Floorplan availability and naming follow Keystone's 2026 model-year literature and RVUSA's structured records. The two catalogued plans (3800FL, 3900RK) are part of Keystone's wider-body refresh and are still being added to the structured-spec databases; they will be built out with full RVUSA-verified specifications once those records publish. All thirteen profiled plans above link to complete pages with verified weights, capacities and floorplan detail.
04 Montana High Country — the lighter sub-line
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 and the four-season build, on a standard-width chassis with Ground Control electric auto-leveling (the flagship Montana uses hydraulic Level-Up). 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 or heavy half-ton-plus setup. The 2026 High Country line is now profiled in full at its own Montana High Country line hub — the roster below links through to the profiled floorplans.
| Floorplan | Layout | Status |
|---|---|---|
| 295RL | Rear living, island kitchen | Profiled |
| 311RD | Rear den | Catalogued |
| 325RK | Rear kitchen, triple slides | Catalogued |
| 331RL | Rear living, high payload | Catalogued |
| 351BH | Bunkhouse, triple slides | Profiled |
| 373RD | Elevated rear den, fireplace | Profiled |
| 377FL | Front living, four slides | Profiled |
| 381TB | Two full baths, two bedrooms, loft | Profiled |
| 385BR | Mid bonus room, loft, outdoor kitchen | Profiled |
| 389BH | Bunkhouse, four slides, king bed | Catalogued |
| 397FB | Two full baths, four slides | Catalogued |
Montana High Country is a separate, lighter sub-line from the luxury Montana profiled above; its plans carry their own dimensions, weights and GVWRs, now verified with RVUSA-structured specifications at the High Country hub, where six floorplans are profiled in full and five more are catalogued.
Model year: the roster and the High Country cross-link above describe the MY2026 line and stay accurate as such. Keystone is now shipping MY2027 Montana High Country units (391TB, 290RL and 300RK appear in dealer stock). The MY2027 roster is not yet profiled here. Checked 29 Jul 2026 against MY2027.
05 Family & model-year notes
Luxury Montana vs. Montana High Country — shop the split first
The Montana name covers two distinct fifth-wheel lines. The luxury Montana profiled here is the full-size, taller, heavier flagship on the line's 18,000-pound GVWR. Montana High Country is a deliberately lighter, lower-profile sub-line built for easier towing and storage. They share brand DNA and four-season construction but differ in size, weight and price — decide which line fits your truck and use before comparing floorplans.
Redesigned widebody rolling out for 2026
Keystone has begun refreshing the Montana with a wider body for the 2026 model year — the new 3100RL hero adds five inches of interior width, triple air conditioning and a heavier Curt 8,000-pound chassis with anti-lock brakes, and new plans (3800FL, 3900RK) are appearing on Keystone's site. Because the redesign is mid-rollout, some figures on the newest plans are derived and flagged pending factory publication; weigh any loaded coach and confirm the build sticker.
Watch payload on the largest plans
Because the luxury line shares a 18,000-pound GVWR, the longest, heaviest plans have the least payload left over — the family 3857BR leaves about 2,382 pounds and the full-timer 3941FO about 2,356. For full-timers carrying tools, water and a household's belongings, that margin disappears quickly. Treat brochure pin weights as a floor, weigh the loaded coach, and match it honestly to your truck's payload and rear-axle rating.
Four-season build is a genuine differentiator
The Four-Season Living package — a heated, enclosed underbelly with forced hot air and electric tank heaters, zero-degree tested — together with the 12-inch I-beam z-frame chassis, 2-inch laminated fiberglass walls and the fully walkable Alpha TPO roof is central to Montana's positioning as a true full-time, all-weather coach. The construction figures on these pages follow Keystone's published specifications.

Coverage is not complete, and this matters. These campaigns come from two passes over NHTSA’s public record: a query-by-query harvest of the recall API (1,556 queries, of which 0 failed and 242 returned an explicit zero), and a sweep of NHTSA’s complete recall flat file (325,650 rows), which added 46 campaigns the API harvest had missed. It missed them because the roster it worked from was built by a catalog endpoint that refuses most requests, so entire manufacturer names were never asked about — NHTSA files several Forest River sub-brands as makes of their own. Two limits remain: NHTSA sometimes files a roster under a parent name, and some matches below rest on the wording of the recall rather than its model field. Campaigns affecting only pre-2005 units fall outside this catalog’s range and are not listed. This page is a starting point, not a clearance. Check a specific VIN at NHTSA before you buy, and again before you tow.

How this count is drawn. A report is counted here only when NHTSA’s own model field names this line. What the owner typed in the description is never used to attribute a report: our line names are ordinary English words, and an owner writing “imagine my surprise when the axle went” or naming the state of Montana is not reporting a Grand Design Imagine or a Keystone Montana. The total does include reports NHTSA filed under this line’s own trim badge — Montana-Big Sky — because it names the same trailer. Held out of it: Montana Mountaineer and Montana-Mountaineer (Mountaineer is a separate Keystone line we do not publish).
Read these as reports, not as findings. Complaints are submitted by owners and NHTSA does not verify them; no complaint here has been confirmed as a defect, and none of them is a recall. The sample is also self-selected — only owners motivated to file appear in it — so a high count tracks how many units a line sold at least as much as how well it was built. Use the pattern, not the total: a component that keeps recurring is worth inspecting on any used unit. File or search complaints at NHTSA.
