Abstract: A trailer to be towed by a pickup truck or the like having a rear cargo space mounting a fifth wheel coupling and adapted primarily for transporting vehicles, such as racing cars. The trailer has a frame with a rear, relatively low cargo bed for supporting a vehicle to be transported, a front elevated hitch tongue for pivotal connection to the fifth wheel coupling of the pickup truck. The longitudinal members of the frame are bent to a unique S-shape or gooseneck shape and have curved front extremities joined to one another in such a way as to minimize stress concentrations in the members and provide a relatively strong and rigid frame.
