I am looking at adding some fuel capacity and considering either an Al tank or plastic tanks in the bed. I haven't found any plastic tanks I like, so that may be a moot point. But I can build a large Al tank for the bed. The question is about compatibility. I have read that SVO and Bio can be problematic in steel tanks, how does this effect Al. Also if I primarily run Bio or SVO in the big AL tank would there be any problems with running regular diesel in the tank as well, say I can't find bio or SVO on a trip.
Thanks with the smog check discussions, crappy ULSD and the price of regular diesel I am considering all options to keep the truck running cleanly, efficiently, affordabley and reliably.

All types of diesel are fine in aluminum as are bio fuels such as biodiesel and SVO. Most fuel tanks on larger trucks are either steel or aluminum. The only issue with steel tanks is if they are galvanized.
