    AI summary

    The Keystone Montana 3123RL flips the typical fifth-wheel script by putting the living area in the rear, where a large rear window and 5K BTU fireplace create a surprisingly residential feel. Up front, the east/west Queen bed keeps things practical without sacrificing comfort, and owner favorites like the lift-up bedroom dresser and generous master closet make the space feel genuinely livable. The kitchen holds its own too, with a farmhouse sink, solid surface countertops, a high-rise pull-down faucet, and a full island that doubles as prep space and a gathering spot. Washer/dryer prep, La-Z-Boy furniture, central vacuum, and the MORryde suspension package round out an interior that punches well above the typical towable experience.
