Well the Wilcox alloy tanks are works of art and the prices match. The NormanHyde tanks aren't really worth even those prices for a few tenths of a gallon more...so there is not a reasonable solution to a larger Bonnie tank out there. I guess you can always carry an extra gallon or two or three with an auxiliary tank. Oh well, thought someone had found a more reasonably priced larger tank out there that I hadn't heard of before.
I suppose I will be stopping every 130-145 miles for fuel as before.
