2026 Keystone Montana3761FL

The 3761FL inverts the usual fifth-wheel layout. Instead of a rear living room, the lounge moves to the front, up in the raised section over the pin, where five slide-outs open an expansive entertaining space with opposing sofas and theater seating. Behind it sit a full central kitchen, a private bedroom, and — the plan’s signature — a bath-and-a-half, with a second half bath that is the feature full-timers and entertainers most often want.

Five slides is the most of any profiled Montana, and the layout is built for living rather than berth count. It carries the standard luxury build — 12-inch I-beam z-frame chassis, Alpha TPO walkable roof, the Four-Season package, the La-Z-Boy furniture package and an 18-cubic-foot residential refrigerator on a 2,000-watt inverter — with a king bed, a 50-inch living-room TV and a single 15,000-BTU Coleman Mach heat-pump air conditioner standard. RVUSA lists a 2,880-pound dry pin and a 3,049-pound payload against the line’s 18,000-pound GVWR.

At an MSRP of $130,433 it sits in the heart of the luxury range. For a couple or a pair of couples who want the biggest, brightest living space in the lineup and a second bath — and who tow with a properly rated three-quarter-ton or one-ton truck — the front-living 3761FL is the entertainer’s Montana.

Montana is Keystone's flagship luxury fifth wheel and the best-selling luxury fifth wheel in North America. 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 3761FL on this page is highlighted; each other profiled plan links to its own page.
