So when I bought this truck it already came with the flatbed.

Had a aftermarket class IV reciever hitch and no spare.

Automatically I knew I was gonna be installing the oem class V hitch. I did not want to alter it in any way due to if I come across a bed I can't refuse it would have the brackets and such such for the bumper. So I knew I needed to extend it.

This bed was made for another vehicle. They don't manufacturer this kind anymore and the frame had been cut up a bit to fit around the shock mounts and leaf spring mounts.

The weekend before doing the work I started measuring and low and behold! I honestly didn't even notice it the whole time, the gooseneck location was actually forward of the rear axle.

So got some rough measurements and got some material.
