Why not just buy a diesel if you require this much towing capability?
My notoriously hated 05 PSD with the 6.0 averaged 15-16-mpg loaded to the gills hauling a 3 horse trailer with living quarters, 3 fat mares, tons of excess junk and other items when we moved from WV to Florida, over 975 miles.
Not everyone hauls 20k lbs every day. A more powerful gasser is the ticket. The operating cost are much higher for a diesel. Back when diesel was cheaper than gas you may have made the numbers work. Now diesel is $.60-.80 higher than gas. Never mind DEF, particulate filters, and all the other nonsense on diesels now.
I also had a 6.0. It was used to pull duel tandam 20k trailers every day. It got less than 10 mpgs pulling a load. I'm going to question your loaded mpg numbers.
Diesels were literally regulated out of the market! Started with Low Sulfur fuel, idiots didn't want to see Big Rigs rolling coal, and yes diesel should be cheaper than gas.
