If memory serves (which it frequently doesn't these days), I had to sit myself up between the fender and the frame, reach in between the bed and frame and remove the fuel supply and return lines before dropping the tank. Then I loosened both bands a little, then undid the front, then the back. I think I dropped it onto a creeper so I could roll it out.
If/when I do it again, I'll replace the stock pickup with a Draw Straw.
With a 1/4 tank, it wasn't too tough, even for an old guy.
