This attachment is to add coolness to your ride when not dragging a trailer around behind. It can drop in on any standard pickup truck or van trailer hitch. The skull is about 6" tall. It's made of 3/16 inch thick stainless steel and has been given a very durable black powder coat finish. Thanks for checking it out! And as always if you have any questions or a custom design, let me know and I'll see what I can do. Thanks again.
