Since you'll be towing, pay particular attention to any indication of spark knock/detonation with aged fuel. It might be smart to also add some octane booster (available at parts houses) to be on the safe side, since fuel can lose some octane rating over time.

After you burn around half of the tank, fill up with fresh fuel to dilute the old. After a couple of tanks have been burned, repeat the BG-44K treatment.
