The Keystone Montana High Country 373RD is a luxury fifth wheel known for its unique elevated rear den and massive storage capabilities. It’s a popular choice for families or couples who want a residential feel while on the road.

Standout Features

  • Elevated Rear Den: The “RD” in the name stands for Rear Den. This area is raised above the rear storage, creating a cozy, separate living room with theatre seating, dual hide-a-bed sofas, and a 50″ Smart TV with a fireplace.

  • Massive Exterior Storage: Because the den is elevated, it allows for a giant pull-out storage tray in the rear, perfect for bulky gear like bikes, kayaks, or large bins.

  • Residential Kitchen: Includes an 18 cu. ft. residential refrigerator with an ice maker, a dedicated coffee station, solid surface counter-tops, and a 24″ Furrion stove.

  • Master Suite: Features a King-size bed (standard), a large wardrobe with washer/dryer prep, and a bathroom with a dual-sink vanity—a rare luxury in many RVs.

  • Four-Season Living: Equipped with 12V heat pads on holding tanks, an insulated underbelly with forced hot air, and tested for 0°F usage.

Technical “Keystone Exclusives”

  • Blade Pure™ Airflow: A high-performance vent system designed to provide 20% more cooling air than standard systems.
