The CURT Q20 features a gross trailer weight capacity of 20,000 lbs. and can accept a vertical load limit of 5,000 lbs., giving it the capability to tow most large recreational vehicles, campers and many other 5th wheel trailers. Also like the Q24, the Q20 5th wheel has a superior hitch head, pivoting on a spherical axial bearing. This ensures smooth, quiet towing and allows unimpeded head movement and a wide turning radius for your trailer. The self-aligning head and dual-locking jaws make coupling easier, and the three-position coupling mechanism indicates when it safe to couple and when it is safe to tow. The Q20 comes with a durable carbide powder coat finish to give this hitch the best possible defense against corrosion, scratching, UV damage and whatever else you throw its way. It is tested in accordance with SAE J2638 for safety and is also backed by a limited lifetime warranty to give you peace of mind. This 20K 5th wheel hitch head comes attached to the CURT R20 slider and a set of 5th wheel rails to be mounted in your truck bed using a 5th wheel bracket kit. CURT 5th wheel sliders feature solid construction and offer a sturdy mounting place for your 5th wheel hitch, ensuring that none of its towing strength is lost. CURT 5th wheel sliders are also true rolling units, meaning they actually roll on wheels that bear the weight of the trailer rather than simply sliding on hollow rods as seen in competitive models. With a thick operating handle, the roller smoothly rolls the 5th wheel head forward and back, locking securely into each position as desired. CURT sliders also provide up to 12" of displacement as well, unlike the more common 10", to give you a wide range of motion and plenty of space to get your RV or other 5th wheel trailer around any turn. Certain turret-style pin boxes, such as Sidewinder, are not compatible with CURT Q-series hitches and should not be used as they may create vehicle / trailer handling hazards.
