This bed is designed to be used with or without the Heavy Oilfield truck frame and winch I also offer in my store. The bed is a scale 10' wide and 33 feet long including the headache rack. The buyer/builder will need to provide a small wire or brass rod for the pivot points of the poles, and the center Tommy Moore block. The file has passed the normal software checks for the Frosted Detail materials. Should there be a problem, contact me via the desinger link, or directly via email to modelmechanic@gmail.com
