    AI summary

    The 370FLMB packs a surprising amount of living into its layout — a dedicated bunk room sits mid-coach between a front living area with fireplace and a private rear bedroom with an east/west King bed and rear window. The loft adds flexible sleeping or storage space, and the farmhouse sink and kitchen island give the cooking area a genuinely upscale feel. Owners consistently call out the storage as exceptional, and the washer/dryer prep is a practical touch that makes longer trips far more comfortable. Bathroom access with slides in is a nice detail that keeps things functional even at a tight campsite.
