An extra 150 gallons is nice. That's 42% more range.

Very nice.

What material are your tanks?

350 gal, I figure we've got 1200nm (2gph @ 7.5k) easy and probably 1600
if we go slow. I am going to add some fuel capacity by putting bladder
tanks under the aft cabin. I think we can add another 150 gal that way.
