Good choice on a V8 gas. Bigger the better,except for the 5.7. The 5.0 is a good engine. That's what I have in my '12 F150 FX4. I pulled a John Deere tractor from Corpus to my ranch and averaged 11.5 mpg. I usually get 16.5 mpg,average highway/city. My son has a '14 F350 FX4 w/6.2 gas. He gets 11-13 mpg empty.
Unless you are towing heavy loads a lot,diesel is a money pit.

I keep an eye out for you.
