  • Dual Vanity Sinks
  • Desk
  • Fireplace
  • Residential Refrigerator
  • Kitchen Island
  • MORryde Solid Step


This Montana High Country is the perfect full time fifth wheel for couples that love to travel.  The rear kitchen layout offers a 18 cu. ft. residential refrigerator and a residential microwave oven for all of your cooking needs.  There is even a built-in desk for those who need to do a little work while away, or for those lucky telecommuting workers who can work from just about anywhere!  For inside entertainment, you will enjoy the power theater seating with a USB port opposite a cozy fireplace and telescoping HDTV. There is also a hide-a-bed sofa for more seating or sleeping space for guests who wish to stay for the night.  A private front bedroom gives you a little space away from the main living area to retreat to when it is time for bed, and you will love the dual vanity sinks in the bathroom, as well as all of the storage space both inside and out!


When heading out and setting up in a Keystone Montana High Country fifth wheel you will appreciate the Dexter E-Z Lube axles, Max Turn front cap and radius frame with Hitch Vision, and an enormous drop frame pass-through storage compartment to name a few features. Inside you will find luxury and comfort with the 78" tall main slide outs and flush mounted LED interior lights. The bath features a skylight over the shower, seamless countertops, and a vanity with three drawers for extra storage space!. The chef of the family is going to love the Montana High Country's kitchen with its Furrion 21" two in one stainless steel cooktop and oven, a 30" over-the-range microwave, solid surface countertops, and a high-rise faucet with an integrated pull-out sprayer, plus so much more!
