I'm going to add tanks like that on each side when I get done with some of the higher priority projects. I like the idea of going hundreds of miles between fill-ups. I would like to add fuel senders and a switch to show the amount of fuel in each tank on the fuel gauge. I'm going to weld up the filler and just not use one, and run vent lines from the aux tanks to the in-cab tank. I'll gravity feed from the in-cab tank to each aux tank by using valves in the fuel lines. It may take me extra time to fill up, but that sounds fine to me.
