    Keystone RV Alpine fifth wheel 3712KB highlights:

    • Separate Living Area

    • Dual Sink Bath

    • Two Pantries

    • Kitchen Island

    • Patent-Pending Windshield

    • LCI Solid Step

    The whole family will enjoy camping in this Alpine fifth wheel! The private bedroom is decked out in comfortable features like the king bed with storage underneath, two wardrobes for your hanging clothes, and a chest with a TV space above it. You even have access to the rear full bathroom which features a double sink vanity so that two can get ready at once, a walk-in shower, and an area prepped for the optional washer and dryer. The front living area offers a separate space to relax and unwind while watching the 50" LED TV with fireplace below or gazing out the windshield.  There is plenty of seating and sleeping space as well.  Cooking in the kitchen will be a breeze too thanks to the kitchen island, the convection microwave, and the walk-in pantry!  You might even like to upgrade the 18 cu. ft. gas/electric refrigerator to a residential refrigerator option.

    When you choose an Alpine fifth wheel by Keystone RV, you are choosing luxury, innovation, modern style and so much more! The stunning Aspen Oak cabinetry with contrasting Renewed Oak accents and vintage wire mesh glass inserts, the polished natural stone solid surface countertops, and the varied plank width resilient flooring throughout are just a few highlights inside. Some other noteworthy features include the high-fidelity video and audio to withstand road vibration with three, separately controlled sound zones with smartphone app capability, and the iN-Command system with oversized touchscreen monitor giving you control of the slides, awnings, and HVAC. Each Alpine is built with 100" wide body construction, a dual 15,000 BTU Whisper Quiet A/C system, a Nautilus On-Demand water heater for instant, endless hot water, and insulated wrapped tanks with 12 volt heat pads allowing you to travel every season.
