Keystone Cougar fifth wheel 357UMR highlights:

  • Fireplace
  • Theater Seating
  • Rear Mud Room
  • Hitch Vision™
  • Outside Shower
  • Dual Entry


This Cougar fifth wheel is amazingly unique because of the rear mud room that has its own exterior entry door! When you step foot into this space from outside, you'll see a pet-friendly utility shower to your left that you can use to wash off your dog's paws after playing all day out in the mud. There is a washer/dryer cabinet, so this space can also be used as a laundry room while you're out on the road, and you can even fold your clothes or store laundry baskets on the desk with overhead cabinets. Talk about residential living! When you make your way out of the mud room and into the main living area, you'll find even more homey comforts with the theater seating, sofa, kitchen island, fireplace, and LED HDTV. You'll also have plenty of space with opposing slides on either side. The front portion of this unit has a private bedroom that you can escape to each night, and there is a full-height wardrobe in the bedroom for great clothing storage.


Spend more time having fun and less time worrying about your RV with the Keystone Cougar fifth wheel! These units have all that you will need for excellent vacations. The interior comes with 5/8" one-piece DynaSpan® flooring, tall slide outs for added comfort and head room, night roller shades throughout, residential, raised-panel hardwood cabinet doors and drawers, decorative crown molding, a 5,500 BTU electric fireplace with thermostat control and remote, and a Max Air exhaust fan with rain sensor. The exterior is also fully outfitted with a convenience center, friction-hinge entry door, electric four-point auto leveling system, an LCI® SolidStep® on main entry, a full pass-through storage with slam-latch baggage doors, an industry-best 80-gallon fresh tank capacity, a 2" accessory hitch with 300-LB storage capacity, and an outside shower.
