I get pretty good mileage on my 6.7L F250, max is up to 24.5mpg in city/highway combined. I'm pretty certain any of the major brands newer diesels can do just as good. I don't think the brand is what will determine your mileage but instead it is mostly the driver.

You're not going to find anything that has great mileage while towing.

Ur right it depends on the driver. I press lightly when it's traveling 75mph and computer says 30 mpg already. I drove 40 miles and the remaining miles
Went from 400 to 440. It even increased. Lol.
