    The Used 2021 Keystone RV Alpine 3910RK is a luxurious rear-kitchen fifth wheel designed for RVers who want residential-style comfort and plenty of space for extended stays. At 43' long, this three-slide floorplan combines a spacious rear kitchen, expansive living area, private front master suite, and bath-and-a-half layout. With a king-size bed, theater seating, fireplace, residential-inspired kitchen, and generous storage throughout, the Alpine 3910RK is built for comfortable family camping, seasonal stays, and extended adventures.

    The 3910RK has a 13,517-lb. dry weight, 2,780-lb. hitch weight, and approximately 2,983 lbs. of cargo capacity. It measures 43' long, 8' 4" wide, and 13' 3" high and provides 54 gallons of fresh water, 83 gallons of gray water, and 83 gallons of black water. The three-slide layout significantly expands the usable interior space, while dual exterior awnings create additional outdoor living space.

    Rear Kitchen

    The rear kitchen is one of the defining features of the Alpine 3910RK. Its wraparound design provides excellent workspace and storage while giving the cook a clear view into the living area. The kitchen's residential-inspired layout makes it especially well suited for preparing full meals during longer stays.

    The kitchen includes:

    • Extra-deep stainless-steel dual-bowl sink

    • High-rise faucet with sprayer

    • Hardwood cabinetry

    • Free-standing dinette with storage

    The 2021 Alpine also features Aspen Oak cabinetry, polished natural-stone solid-surface countertops, and a high-contrast backsplash that give the interior a bright, residential-inspired appearance.

    Living Area

    The spacious living area benefits from the three-slide configuration, creating plenty of room for relaxing and entertaining. Theater seating provides a comfortable place to settle in, while the tri-fold sofa sleeper offers additional seating and sleeping space. A fireplace and 50" LED TV create a welcoming entertainment area, while the Jensen audio system provides multiple entertainment zones throughout the coach.

    Front Master Suite

    The private front master suite provides a comfortable retreat with a 70" x 80" king bed, decorative headboard, bedside reading lights, and convenient outlets. The bedroom connects to the front bathroom, creating a true master-suite experience. A large walk-in wardrobe provides additional storage, while the bedroom is also prepared for a washer and dryer.

    Bathroom

    The Alpine 3910RK features a bath-and-a-half layout, providing a convenient half bath for guests while reserving the larger front bathroom for the bedroom suite. The main bathroom includes a spacious shower with a seat, shower skylight, porcelain foot-flush toilet, medicine cabinet, and linen storage. An on-demand water heater provides hot water for everyday camping needs.

    Exterior & Camping Features

    Outside, the Alpine features 20' and 11' Carefree power awnings, providing generous covered outdoor living space. Additional features include large exterior storage, an exterior shower, 50-amp electrical service, power cord reel, hydraulic leveling system, and a 2" receiver hitch. The Alpine's laminated sidewalls, double-welded aluminum construction, heated and enclosed underbelly, and Polar Pack four-season protection add functionality for a variety of camping conditions.
