2026 421FK Features and Options

Forest River RiverStone fifth wheel 442MC highlights:

  • Full and Half Bathroom
  • Rear Den
  • Private Bedroom
  • Desk
  • Two TVs

 

This RiverStone fifth wheel has an amazing den in the back! This area is not only an excellent lounging space with its theater sofa, hide-a-bed sofa, and entertainment center, but it is also a comfortable guest suite because it contains its own half bathroom and a drop-down queen bed. Each section of this unit has opposing slides, so you'll have plenty of living space, and the kitchen area has a pull-out dinette so that you can sit down with hot meals each night. You have a large pantry for snacks and an 18-cubic foot French door refrigerator with ice maker for cold beverages. The ceiling fan allows you to cool off the interior without overworking the AC, and the cordless vacuum will help you clean up messes. 

 

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.
