The 2026 Keystone Montana 3900RK represents a major refresh for Keystone’s flagship luxury fifth wheel lineup, marking 25 years of the brand. The “RK” stands for Rear Kitchen, but this specific floor plan is heavily engineered around a residential, long-stay lifestyle.

Key Floor Plan & Interior Highlights

  • The Ultimate Rear Kitchen: Built like a residential home rather than a traditional RV kitchen. It features massive solid-surface countertops, matching backsplashes, a deep stainless steel single-basin sink (with dishwasher prep), a 4-burner Furrion stove/oven, and a 20 cu. ft. 12V refrigerator. It also includes a dedicated pantry and a built-in bar with a wine refrigerator.

  • Mid-Ship Living Area & Workstation: The living room features an expansive, L-shaped reclining sofa that converts into a sleeper. It faces a 65” Smart TV with a JBL sound system and a 5K BTU electric fireplace. In the 7-foot-tall slide-out, there is a pull-out dinette that seamlessly doubles as an adjustable sliding workstation/desk.

  • Guest-Friendly Half Bath / Mud Room: Just inside the main entry door is an oversized half bath. It doubles as a utility room, featuring stackable washer/dryer prep so you don’t have to sacrifice closet space in the main bedroom suite.

  • Front Primary Master Suite: The front of the coach is a private oasis with a king-bed slide-out, a second fireplace, and a dresser with a dedicated TV. The primary bathroom spans the front cap and includes dual vanity sinks, a 30″ x 48″ residential fiberglass shower, and a massive walk-in closet complete with a built-in jewelry center and a charging station for a cordless vacuum.

Exterior & Construction Features

  • Storage Solutions: Includes a massive, unobstructed pass-through storage compartment with a premium oversized steel slide-out tray, plus dual pull-out gear trays at the rear bumper.

  • Outdoor Entertainment: Features an exterior 50” TV under dual Lippert 12V electric patio awnings (14′ and 18′) equipped with LED lighting.

  • Four-Season Package: Tested and approved for $0^\circ\text{F}$ usage, featuring 12V heat pads on holding tanks, Astrofoil insulated slide floors/underbelly, and a 60K BTU Suburban on-demand tankless water heater.

  • Tech Ready: Comes with factory Starlink roof prep, a Furrion Vision S side/rear observation system, and the Giggy Box 12V distribution system.
