2026 Keystone Montana3941FO

The 3941FO is the Montana for people who live in it. Its signature is a dedicated front office — a proper workspace up in the raised front section rather than a convertible dinette — which makes it one of the few fifth wheels purpose-built for remote work on the road. Behind it, five slide-outs open a large kitchen with a pantry, a full bath, a bunk room and a rear private bedroom, and an outside kitchen moves cooking into the open for long stays.

It is equipped as a residence. A confirmed 2026 unit carries roof solar with an inverter, a washer/dryer, a fireplace, an 18-cubic-foot residential refrigerator and the full luxury build — 12-inch z-frame chassis, walkable Alpha TPO roof, Four-Season Living package and La-Z-Boy furniture — with a king bed and a single 15,000-BTU Coleman Mach heat-pump air conditioner standard. Camping World’s 2026 unit lists a 15,644-pound dry weight against the line’s 18,000-pound GVWR, which leaves roughly 2,356 pounds of payload, with a 2,810-pound dry pin.

At an MSRP of $137,153 it is among the priciest plans in the line, matching its full-timer intent. The payload figure is worth weighing carefully for anyone genuinely living aboard — a full-timer’s belongings, tools and water add up fast. The grey and black tank figures shown are the Montana luxury-line typical and are flagged pending a plan-specific factory confirmation. For a remote worker or a full-timing couple who need an office, an outside kitchen and a rear bedroom suite, the 3941FO is the Montana built for the job.

Montana is Keystone’s luxury fifth-wheel line. The line runs to fifteen floorplans for 2026; the six highest-demand layouts are profiled here in full, and the rest — along with the lighter, lower-profile Montana High Country sub-line — are catalogued on the line hub. The 3941FO on this page is highlighted; each other profiled plan links to its own page.

A full 70-gallon fresh tank is about 584 lb of water (water counts as cargo: 49 CFR 571.120 S10.4.2), 25% of the 3941FO’s 2,356 lb cargo capacity, leaving 1,772 lb (295 lb per rated berth). Across 13 Montana floorplans the water share runs 15% to 28%, and 1 gives up more than this one. Nearest on that share: Montana 3857BR at 25% and Montana 3532SP at 28%. Your own unit’s figure is on the label inside its entry door (49 CFR 571.120 S10.4.3).
