If all you want to remove is the bed wood you should be able to remove the bed strips and the bolts through the angles that go through the bed wood. Start in the middle and work your way to the sides. The edge board should slide out from under the angle but may take a little pursuasion.
If you want to remove the bed sides and front panel there are a lot of bolts to remove starting with the rear fenders.
Seems a shame to take it apart, it looks pretty good the way it is.
