More often than not, one part that rusts before the rest of the pickup is the truck bed itself. Replacing the bed and buying a brand new one is oftentimes costly and inconvenient, as the new bed will do the exact same thing (i.e., rust) over time as well. However, there is an alternative that exists in building your own flatbed that will last for years to come, as well as save you a pretty penny. Follow these simple steps to build a simple wooden flatbed for a pickup.

  1. 1

    Crawl under the truck and use the socket set to loosen and remove the lag bolts holding the truck bed to the cross-members of the frame. Have someone assist in lifting the bed free from the frame and laying it somewhere for disposal.

  2. 2

    Cut one of the decking boards in half and then use the lag bolts to bolt the two halves lengthwise across the pickup frame. Lay the other decking boards side by side on top of the lengthwise boards and screw them down tightly with the wood screws.

  3. 3

    Mount your taillights and bumper on the rear of the bed with the hardware provided in your lighting kit and hang your number plate on the rear middle section of the bed.

Tips and warnings

  • To reinforce the bed, sheets of diamond plate metal can be screwed down on top of the flatbed boards.
  • Check local and state laws, as some laws require fenders to be on the vehicle in order for it to be legal.
