Benefit of extra fuel tank.
I just went 1237 miles between fuel stops. I towed for about 600 hundred of those miles. I've got an extra 90 gallons in the truck bed. With rising fuel prices it's nice to avoid the gas station.

Personally, I would never even think about either replacing a good factory fuel tank with a larger tank or adding an auxiliary tank.
If you want more capacity solely to buy cheaper fuel, it will take one heck of lot of fill-ups to pay back anywhere near the out of pocket cost. If you do it for longer stop intervals, I easily get two bathroom stops out of a tank of fuel with my existing tank.
Adding more fuel at 6-7 pounds per gallon never made any sense to me.
