Ford F350 7.3 Gas Pulling 15k

I had the opportunity to drive a new 7.3 gas Super Duty today. That new 10 speed trans worked great. I was amazed how the whole vehicle performed. I would wander if anyone has had the opportunity to experience the fuel mileage either while towing or without. If it isn't significantly worse than that of our '16 250 Super Duty with 6.2, we may just make the step up provided we locate the package that has the options we currently have. It might take time as we might have to wait till the factories get back to work.
