Comfort, Convenience & Adventure in One Easy-to-Tow Package: The Keystone Cougar X-Lite 21RBS is the perfect travel trailer for couples or small families looking for a lightweight camper without sacrificing comfort. At just under 26 feet long and weighing approximately 5,200 lbs dry with dual axel suspension, it's designed to be towable by many half-ton trucks and larger SUVs while providing the amenities of a much larger RV. It comfortably sleeps up to four people and features a spacious rear bathroom, a private front queen bedroom, and a large slide-out that creates an open, inviting living area.
