New 2026 Keystone COUGAR Half Ton 28 RLI

The 2026 Keystone Cougar Half Ton 28RLI redefines what's possible in a 33-foot rear-living fifth wheel, delivering an impressive 41 feet of continuous counter space typically reserved for luxury models. This thoughtfully engineered floorplan features a front king bedroom, opposing slides for enhanced livability, and a gourmet kitchen with an island layout that prioritizes real-world functionality. Built on Keystone's individually engineered structural I-beam chassis with heavy-duty 5,100-pound axles featuring ABS brakes, the 28RLI incorporates advanced towing technologies, including the Helix series coil-spring pin box and Road Armour shock-absorbing suspension system, for confident highway performance. The Climate Guard Protection Package extends your camping season with zero-degree rated protection, while HyperCore composite wall construction with Azdel inside and out provides superior strength and insulation.

Premium features throughout include electric four-point auto-levelling, dual electric awnings with LED lighting, and an 18,000 BTU Furrion Chill Cube air conditioner for superior cooling capacity. The interior showcases residential shaker-style hardwood cabinetry, dimmable LED lighting, night roller shades throughout, and a 12-volt 10-cubic-foot dual-swing refrigerator for convenient access from both the entry and kitchen. Keystone's attention to detail is evident in factory-installed upgrades like the Oxygenics shower head, bedside USB outlets, and in-floor heating ducts for efficient climate control. With an industry-leading 55-gallon fresh water capacity, MaxTurn Technology for improved maneuverability, and rack-and-pinion slideouts for reliable operation, the 28RLI delivers the perfect balance of towability, livability, and premium appointments for serious RV enthusiasts.
