Description

The 2026 Sierra 3900HBLR is a full-size fifth-wheel built for comfort and long-haul living — featuring a rear living layout, kitchen-island, bath-and-a-half convenience, and construction/features meant for heavy use and comfort, ideal for long trips or extended stays.


Interior Features

  • Spacious rear living area with slide-outs provides a large lounge setup (sofa / hide-a-bed, entertainment center, optional fireplace, panoramic windows) for relaxing or entertaining.

  • Well-equipped kitchen with solid surface countertops, stainless-steel appliance package, 16 cu. ft. 12V refrigerator, 3-burner oven/range, under-mounted sink, hidden-hinged soft-close drawers and cabinets, decorative backsplash, and ample storage for extended travel comforts.

  • Bedroom suite with king bed, memory-foam mattress, plenty of storage (dresser, wardrobes), and a large walk-in bathroom closet adjacent — providing a private and roomy master suite.

  • Full bathroom includes a fiberglass one-piece shower (with seat), porcelain foot-flush toilet, vanity, and generous counter/linen space; there’s also a half bath (bath-and-a-half layout) for extra convenience on longer trips or when guest-sharing.

  • Interior finishes and comfort touches: wood-inset cabinet doors, solid-wood drawer fronts, large picture windows, recessed residential-style lighting, LED lighting throughout, accent lighting over dinette, and “home-like” linoleum flooring.

  • Washer/dryer prep included — nice for extended stays or full-time RV living without sacrificing comfort.


Exterior & Construction Features

  • Heavy-duty build: 7,000-lb axles, Goodyear radial tires, anti-lock brakes, underbelly armor, powder-coated cambered frame with rust prohibitor — giving durability and stability on the road or at campsite.

  • Automatic electric leveling system and power front jacks for easier setup.

  • Dual electric awnings (12′ & 18′) with LED light strips for outdoor living/entertaining space and shade.

  • Tinted, large panoramic windows with UV protection; spare tire, passthrough storage with heavy-duty slam-lock baggage doors; LP quick-connect, dual 30-lb LP tanks with auto-switch — practical convenience and utility for travel & camping life.

  • Solar prep: includes a 200 W roof-mounted solar panel with controller & battery — helpful for off-grid or remote campsite stays.
