6.2 comes stock in the Super Duty. I own a 2019 F250 CC 4WD short bed with the 6.2 and 4:30 gears. Tows like a dream and is rated to carry about 3500 pounds. I average 12 mpg towing a boat that weighs 5K. The 6.2 is as bullet proof as they come.
My ex 2013 Tundra CC 5.7 4WD towed the same boat and got 11 mpg and the azz sagged like a old ladies boobs.
The 7.3 should do an even better job. But its new on the market and some people are complaining about the 10 speed. Add in its an extra cost option at roughly $2,000.
