This file prints the bed, part of a set of three files. There is also a frame and winch available. This is done so the buyer can choose any of the parts or all of them for the complete unit. The bed is a scale 10' wide and 33 feet long including the headache rack. The details I've built in will print in the frosted detail materials only, and is the best choice in my opinion. Should there be a problem, contact me via the designer link or via email to modelmechanic@gmail.com
