A tow hitch is a device attached to the rear of a vehicle, designed to pull trailers or other loads. It typically consists of a receiver, which is a square tube that allows for the attachment of various towing accessories, such as ball mounts or bike racks. Tow hitches come in different classes, each rated for specific weight limits, ensuring safe towing. When using a tow hitch, it's important to match the hitch class with the weight of the load being towed. Proper installation and maintenance are crucial for safety. Many vehicles, including trucks and SUVs, are equipped with tow hitches for added versatility in transporting goods or recreational equipment like campers or boats.
