I hope that someone can reply back to me with this simple question? I have tried to locate this answer on this site...and my questions are more simple than I can find answers.

What is the proper assembly order?

Option 1: Install bed sides, cross member supports first....and then install the wood after the metal is installed?

Option 2: Install the wood on the frame and install the bed metal around the wood.

Option 3: Assemble the metal and wood separately off the truck and put it all on the truck at once?

Does anyone have a good step by step guide?
