I found the bed after looking at the xml files. Its in the store in the misc catagory . it all works fine for me nice truck. On a side note I still haven't found the fifth wheel hitch but I will. The gooseneck and bumper hitches work. You can use the bumper hitch with the pin to pull both trailers and implements
