A year ago I would have agreed with Me Again, but with the 10 speed transmission, these trucks are pretty impressive. We recently received ours and drove it labor day weekend and was pretty impressed, but didn't tow with it. It should have a goose neck hitch on it now. On FTE there's a few ex diesel owners who are reporting they are very satisfied with the towing performance. Most of them have 3.73 gears which is what we have.
These engines don't have cylinder deactivation nor do they have direct injection, and probably won't for the foreseeable future since their primary use is for F250 - F750 trucks. There has been some reported with lifter failures, but those appear to be mostly 2020-2021 trucks.
