Its a ton of work, but, you take all the bolts off on the inside edge of the bed/holding the wood.

under the wheel well there are bolts holding the tub to the bed.
there are blts holding the front to the front bed panel

there are 4 bolts holding it to the rear cross sill, underneth.

take the tailgate off, and in the corner under the t/g trunion there are 2 factory weld beads that need to be cut, I use a angle grinder with a big disk to reach, but have had luck with a chisel, or a hacksaw in a pinch.
