he 2021 Forest River XLR Boost 21QBS is a compact toy hauler that balances cargo capability with everyday comfort. The open garage area makes it easy to bring along motorcycles, ATVs, or gear, then quickly convert the space into usable living or sleeping space once you’re parked. A smart, straightforward layout keeps everything within reach, while the slide-out helps the interior feel more open than you’d expect from a trailer this size. It’s a practical option for weekend trips, trail riding, or anyone who wants flexibility without towing a massive rig.
