I went from a Diesel to the 6.2L Gas. You're right, the biggest difference from my 2002 7.3L Diesel and this gas is the gas mileage and torque. Gas mileage pulling is what I expected, 8.7 mpg on my first trip. The torque is at 405 lbs, about half of what the newer Ford Diesels are putting out. I only pull once a month, so I didn't see the benefit in staying with a diesel.
