I had a 7.3 diesel. Switched to a 6.2 gas. Fuel economy is less but pulls the hills just fine towing. I'm sure the new 7.3 gas will be a bit better towing and worse on gas. I would be more concerned about the tailgate if you are loading anything in the back. Those aluminum gates are one of the reasons why I'm going to stick with a steel body as long as I can.
