The five different types of hitch in the UK are ball hitches, A-frame hitches, tow bars, gooseneck hitches and fifth wheel hitches. Ball hitches use a hitching ball to connect the trailer to a vehicle, while A-frame hitches require a tow bar. Tow bars provide greater stability with heavier loads and can be used with a variety of trailers. Gooseneck hitches are designed for larger trailers, such as horse trailers, while fifth wheel hitches require a special mounting plate in the bed of your truck.
