Gooseneck Low Bed Trailers
Gooseneck low-bed trailers are designed with a gooseneck that connects to the truck via a ball hitch. This design allows for easy loading and unloading of heavy equipment, as the gooseneck can be easily detached, and the front of the trailer can be inclined to the ground.
