Here we review Hitching Systems...

Hitching Systems
The trailer towing industry has developed a classification system that differentiates hitches according to the amount of weight they can tow. This system addresses tongue weight and total weight.  Keep in mind that within each classification are numerous hitches made by a variety of manufacturers.

The three most common types of hitches are the weight-carrying hitch, the weight-distributing (or load equalizer) hitch, and the fifth-wheel hitch, or gooseneck. Weight-carrying hitches are designed to carry all of the trailer's tongue weight. Weight distributing hitches are used with a receiver hitch and special parts that distribute the tongue weight among all tow vehicle and trailer axles. Fifth-wheel hitches are designed to mount the trailer connection in the middle of the truck bed.

When purchasing a hitch, use the recommendations of the manufacturer of the tow vehicle and trailer based on the type and weight page of the trailer. Make sure the hitch has provisions for the connection of safety chains, which are required by most states. When connected, safety chains should have some slack to permit sharp turns but should not drag on the road. In addition, they should cross under the trailer tongue to help prevent the tongue from dropping to the road in the event the trailer separates from the tow vehicle.
