I have no complaints with the diesel version of the truck. The gas version is a bit more rare than the diesel, but from what I’ve read people are happy with them. Payload ratings are in the 2,000- 2,500 lb range for the gassers, fuel mileage 15-17 hwy. The diesel trucks suffer from lower payload ratings like the f250 PSD but have the mass to make for a very stable towing platform. Unloaded hwy mpg for my diesel truck is 20-23 so I tend to drive it more than my old 8.1l gasser that would get 14 mpg down hill with a tail wind.
