Trucks vary in terms of weight and towing weight so knowing which hitch is right for you is very important. B&W has rated their Tow & Stow hitches to tow 10,000 lbs. with the 2’’ shank model, 14,500 lbs. with the 2 1/2" shank model, and 21,000 lbs. with the 3" shank model. This is called Gross Towing Weight Rating (GTWR). The Vertical Towing Weight Rating (VTWR) also called Tongue Weight Rating which is 1,000, 1,450, or 2,100 lbs.
