Has anyone converted a regular bed to a flatbed truck? Can anyone tell me what is involved? I am in for a new fabrication, but would consider purchasing a new deck. I assume I would have to move or alter the gas tank filler tubes, and I have two of them. Also if I go with an aluminum deck, will I need a special gas set up on a mig or a tig to do any welding, or can I get buy with a stick welder with special sticks. My last aluminum trailer required a mig, but that was a few years back.
