Include all of your favorite people on your next adventure in this Montana High Country fifth wheel! Not only is there a rear private bedroom with a king-size bed for you, but there is also a loft above with stairs that take you to the bunk mats. Now your kids will have their own space too. You can even host a few other travelers up front in the separate living room on the two hide-a-bed sofas. This area will be perfect for cozy sleeping because of the fireplace, and you can even watch a movie as you drift off to sleep because of the 50" LCD TV too. The full bathroom has a pivot-hinge door and a 48" x 30" shower with seat, and the kitchen has a breakfast bar that you can sit at to eat your cereal each morning
Live the high life with a Keystone Montana High Country fifth wheel! You'll have all the luxury you need with these units. They come with a Road Armor™ shock absorbing hitch pin, a MaxTurn™ front cap with KeyShield™ automotive-grade paint, a fully walkable roof with Alpha seamless TPO membrane system, and an insulated underbelly with forced hot air and electric tank heaters. The Road Armor™ suspension has 360° vibration control for a smooth ride, and the Ground Control® four-point electric auto-leveling with hitch memory will make set-up quite easy. The interior is elegantly appointed with the Thomas Payne Collection furniture, hardwood decorative slide-out fascia, Beauflor® vinyl throughout with Syntec® woven flooring in main slide outs, accent crown molding, and Sandstone Maple cabinetry.
What a great experience. Absolutely streamlined process of my trade in. I was in and out in just around an hour or so. The staff was super helpful. Cory gave me a walkthrough of my new unit, very knowledgeable staff. I highly recommend this group! - Alex
