The Keystone Montana 3900RK is built around a rear kitchen layout that feels more like a high-end condo than a trailer, anchored by a solid surface waterfall island with four chairs, a high-rise pull-down faucet, and an oversized deep stainless sink. Hardwood cabinetry, backlit crown molding, and dual 5K BTU decorative fireplaces in both the living area and bedroom give the interior a level of finish that holds up even in full-time use. On the outside, the Montana 3900RK earns its keep with a fully walkable TPO roof, hydraulic slideouts on the main level, the Lippert Titan leveling system with a touchscreen, and a 50-amp power cord reel, making setup and breakdown far less of a chore. The optional 18 cu. ft. residential refrigerator with a 2,000W inverter and the MORryde Independent Suspension System are upgrades worth serious consideration if you're putting real miles on it.
