The Knapheide Flatbed is made of diamond plate and smooth steel and has some unique features that are explained by Mike Soich of Knapheide Manufacturing at a Knapheide event in Livermore, CA in October 2010. Mike refers to this body as a "plug and play" body in that it is full-featured and ready to mount and go.
