2026 Keystone Cougar for Sale

The Cougar is one of Keystone's best-selling lines and one of the most cross-shopped towables in its class, spanning both fifth wheels and a deep bench of half-ton travel trailers under the Cougar and Cougar Half-Ton banners. It lands below the Montana and Alpine on price while keeping smart, livable layouts, big slides, and generous storage, and many plans are engineered specifically to be towed by a capable half-ton or three-quarter-ton truck. Fifth-wheel floor plans run roughly 30 to 41 feet, covering rear-living, mid-bunk, and rear-den layouts that suit couples and families. On RV Insider the Cougar averages 3.5 stars over about 197 reviews, with owners praising the floor plans and value, though some report the appliance, slide, and quality-control issues common across the industry. The breadth is the appeal: whether you want a light half-ton trailer or a full-size family fifth wheel, the Cougar family likely has a layout that fits, and used inventory is deep. As always with a high-volume Keystone, inspect the roof, seals, slides, and appliances closely on any used unit.
