I've got one that my Dad built it mounts in the 2 inch hitch receiver. I have the hitch receiver in the middle and I welded another 2 inch receiver out by the edge of the frame. The crane mounts on the outside edge about the same position as if it was in the bed. You can easily take it on and off. The tailgate has to be off to use it. I've only used it once to move a small millstone. If you want I can take some pictures. I think it would be much more convenient then having one mounted permanently in the bed of the truck.
