The front kitchen layout is the 421FK's signature move. You get a full-size French door refrigerator with ice maker, Fisher & Paykel dishwasher, four-burner range with convection microwave, Calcutta solid surface countertops, and a kitchen island with bar seating that would look at home in a real house. The rear King bed suite adds a dual vanity, 40" smart TV, and a dedicated desk slide, so there's a genuine separation between living and sleeping spaces. Residential touches run deep: Truma on-demand hot water, Splendide stackable washer/dryer, 5,200 BTU fireplace, hardwood dovetail drawers with soft-close everything, and two 15,000 BTU heat pump A/Cs keeping both ends comfortable. The automatic 6-point hydraulic leveling and LCI Road Armour suspension make setup and towing far less of a production than you'd expect from a rig this well-appointed.

Forest River RiverStone fifth wheel 421FK highlights:
Kitchen Island
Front Kitchen
Theater Seats
Dual Vanity Sink
Stackable Washer and Dryer
You will feel right at home in this fifth wheel! The rear private bedroom has a 72" x 80" king bed slide for a good night's rest, a rear large wardrobe with the washer and dryer next to it, and even a dresser with a 40" LED TV. And two can get ready at once in the full bathroom with the dual sink vanity. You can then head to either the desk slide to get some work done or whip up some scrambled eggs on the three burner cooktop at the island in the front kitchen. The kitchen even has a dishwasher for easy clean up and two bar stools at the high top dinette that overlooks the middle living area. Relax each night in true comfort on either the E-Z Glide sofa bed slide or the theater seating across from the entertainment center which has a fireplace and 65" Samsung LED Smart TV to watch your favorite movies!
The Forest River RiverStone fifth wheels and toy haulers are luxurious units that have it all! You'll find an automatic six-point hydraulic level-up system to keep your unit in place, and there is preparation for a four-camera observation system. The TravlFi Journey XTR 4G/LTE router and WiFi extender will help you stay connected to the outside world, and you'll never have to overpack again since the Splendid “Astral” stackable washer and dryer will let you clean the small amount of clothes you've brought with you. Another high luxury is the Fischer Paykal dishwasher which will allow you to spend more time enjoying your camp life and less time cleaning up. Each unit is built with a LCI Road Armour suspension system, dual-pane frameless windows, a full docking station, a 200W solar panel, and a BMPro touch control system.
