My set up weighs about 24,500 and l am much happier with a diesel
After owning and driving 18 wheelers for 35 yrs if it isn't diesel l don't want it !
While the long block of a diesel will last a very long time, everything else lasts just as long as on a gas vehicle, only the parts on a diesel are 2-3x as much. Anybody who logged hundreds of thousands of miles knows the light wallet of an injector pump or replacing injectors. Some know both. 6.0 and 6.4 ford's many have felt extremely light wallets with cracked head, broken pistons, and complete engine replacement...well under the high mileage expected. Lots of local oil fleets switched to gas because of these issues. Then the entire vehicle around the engine is the exact same, and wear out at the same rate regardless of what type of fuel goes in the tank. Personally I don't think I'd own a diesel truck much after the powertrain warranty is up. I'll let somebody else foot those huge repair bills. Watched my dad do it enough. Even though he teases me about my hemi, after 40+yrs of truck driving from Texas to the north slope he was the one who talked me out of a cummins. He isn't a mechanic by any means but he has learned a lot of tricks over the years to get home when something breaks down.
If you are towing heavy and logging lots of road miles, heck yeah. Diesel is the way to go. But if short hopping daily driver year round with sub -20 weather and towing under 12-13k, that 6.7 is overkill.
