In stock at Stone’s RV, the 2026 Keystone Cougar Premium 320RDS is a triple-slideout fifth wheel built around a rear living room with serious space for entertaining. At 37 feet long, this unit sleeps 6 people, weighs 11,283 lbs dry with a GVWR of 13,750 lbs and a pin weight of 1,775 lbs, making it a strong match for couples and families who want room to spread out at the campsite.

The 320RDS puts the living room at the rear, separated from the kitchen and bedroom for a layout that feels more like a home than a trailer. The rear slideout holds a large L-shaped sectional with theater seats and a king tri-fold sleeper sofa. A free-standing dinette with bench seat ottoman and two chairs adds flexible seating. The electric fireplace and LED HDTV round out the space. The kitchen sits mid-coach with a 16 cu. ft. 12V refrigerator, 21″ Furrion range with glass stovetop cover, microwave, pantry with dual access to the bathroom, and solid surface countertops throughout.

The front bedroom slideout holds a Platinum Series queen bed with underbed storage. A full wardrobe with sliding mirror doors, a second wardrobe with washer/dryer prep, and a dresser with hidden storage keep the bedroom organized. The full bathroom includes a large shower with glass door and skylight, porcelain foot-flush toilet, solid surface vanity, linen cabinet, and medicine cabinet.

A tankless on-demand water heater, Furrion 18,000 BTU main air conditioner, 15,000 BTU ducted bedroom air conditioner, and 30,000 BTU ducted furnace handle the climate work. The power awning with LED lighting and electric four-point auto leveling round out a well-appointed package. Climate Guard protection and dual-heated holding tanks keep the system running through the full Nova Scotia camping season.
