Hey Troy,
Its all looking good so far!
I replaced my tanks with 2mm stainless, but they were only 120 litres each. Mild steel is probably better for the size you are considering.
I agree with using sockets; There's not enough meat on even heavy plate to tap proper threads.
One other thing. A tank will last a lifetime if you can keep it free from water inside and out.Id recommend installing your tanks on a slight slope, with a sump at the lowest point of each tank. Since mine was flat bottomed, I mounted it on wedge shaped supports (cut from synthetic decking) to slope the bottom down to the drain point. I tied this drain point to a sight glass, so I can immediately see if there is any water in the tanks when I check the fuel level.
