This 42-foot-10-inch premium fifth wheel is an absolute triumph of wide-body luxury, engineered specifically for couples who want maximum workspace, elite comfort, and a grand layout that feels entirely like an upscale brick-and-mortar home. You’ll love the innovative Luxury Rear Kitchen (LRK) design, which wraps around the back of the coach to provide an immense amount of continuous countertop space, keeping the chef fully integrated into the social flow of the living room!

 

The 3840LRK is a masterclass in grand interior design, leveraging a 100-inch wide-body frame to maximize walking paths and remove tight bottlenecks in the hallway and bedroom. The sprawling rear kitchen features residential-style seamless marbled countertops, a massive 16 cu. ft. 12V refrigerator, a deep single-basin stainless steel industrial sink, and stunning city-glass pendant lighting suspended from a custom wood-beam soffit. Just steps away, the central lounge expands via deep slides to create a premium theater environment, boasting Thomas Payne luxury collection theater seating with integrated heat and massage, a legless dinette table with freestanding chairs, a 50-inch LED HDTV, and a 5.5K BTU electric fireplace with remote thermostat control. Up front, the private master suite serves as an upscale retreat, offering a walk-around residential King bed slide-out, a barn-door style wardrobe with stackable washer/dryer prep, and a luxury bathroom with a massive 48" x 30" shower featuring a self-cleaning slow-close door!
