    The Forest River XLR Nitro 351 earns consistent praise for what matters most in a toy hauler: a large garage, a comfortable living area, and storage in all the right places. Owners frequently call it out as a strong choice for both weekend trips and longer stretches on the road, and the layout holds up well whether you're hauling gear or hosting a crowd. Towing gets good marks too, which matters when you're moving something this substantial down the highway. Build quality is a known variable with the XLR Nitro 351, so a thorough pre-delivery inspection is worth the time before you head out.
