Other floor plans with a similar body style, feature mix, and price range, prioritizing other manufacturers and brands.
The Keystone Montana High Country 300RK is built around a rear-kitchen layout that gives the main living space a genuinely open, residential feel, anchored by Thomas Payne theater seating with electric recliners, a 5K BTU decorative fireplace, and back-lit crown molding. The kitchen earns its keep with premium solid surface countertops, an oversized deep stainless steel sink, a high-rise pull-down faucet, and an adjustable sliding "Deskette" with four chairs that doubles as a dining area. Comfort systems are serious: dual Furrion heat-pump air conditioners, a 60K Suburban on-demand water heater, a 35K BTU furnace, and a 65" 4K smart TV paired with JBL 2.1 audio make long stays genuinely comfortable. The Montana High Country line sits in the mid-to-upper-tier luxury segment and tends to earn high marks for livability and layout, though owner reviews are mixed on fit-and-finish consistency, so a thorough pre-delivery inspection is worthwhile.
