You probably need only the 87 octane performance/economy tune. You've pretty much defined what you're looking for in the tune with your post. It's probably pretty close to what I asked for: Good highway passing performance and any improvement possible on gas mileage.
However, since you've got the big tires, you've effectively reduced your gear ratio. I wonder if Bill could write a custom tow tune that would help you even when you're towing THOSE loads? Since tunes are only $30, seems like maybe a reasonable question to ask him.
