I have a CM flatbed that I will be selling. It fits on a short bed single wheel Chevy. I'm sure it can be made to fit other makes easily. It has four buyers toolboxes. Two are 15"x15"x15" toolboxes mounted under the bed and two are 36"x18"x18" bolted on top of the bed ( not pictured ). Send me a message for more information or for my phone number if interested.
