I'll probably intentionally run one tank out of gas on purpose and then go to the pump on the other tank. I'll fill it and notate what the guage says at each 1/4 mark and full. I just want it to be on my terms, not in the middle of the freeway.

I just run a tank until it is just about at E then switch tanks. I'll fill the empty tank when convenient. Keeps the gas fresh in the tanks. Plus the only place that has hoses long enough to reach both tanks is Costco so it is a pain to try to fill both at the same time.
