Just get a optima yellow top battery. I left my headlight on for 5 hours once and my car still started!

yellow top is not good for cold starts.. Actually, it's not made for you to drag 600Ah in a short period of time. It will kill your battery if you use it for start ups.

doubling my power storage but keeping the voltage the same?

will there be adverse gas mileagle effects like the engine cranking to fill the second battery?

obviously..
but as for the gas mileage.... some said that putting more loads on the alternator worsen the gas mileage.... but i just don't think so.
