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" LED TV too. The full bathroom has 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 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 MORryde CRE3000 suspension with wet bolts helps provide a smooth tow, 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, accent crown molding, and premium solid surface kitchen countertops.
