The fifth wheel hitch is a heavy-duty hitch that mounts into the bed of a truck bed right over or just forward of the rear axle. Generally, these hitches are used to haul large campers, travel trailers, and car haulers.
One thing that makes a 5th wheel hitch unique is that the coupling device is a part of the hitch and not the trailer. The hitch receives the king pin from the trailer and then the hitch secures it with with a jaw mechanism.
5th wheel hitches are also only available for pickup trucks.The last cool feature of fifth wheel hitches is that they generally have a pivot capability which allows it to absorb bumps and move with the contours of the road. These hitches can generally hold up to 24,000 lbs. but you still always want to double check.
