If the ONLY reason you're switching trucks is for better MPGs you'll need to drive around the world 7X before it would make sense financially. I get it that a diesel would tow better but you can buy a lot of gas for the amount you'll pay to change trucks.

I have the same truck and same 3.73 gears and am looking at re-gearing to 4.56 which should help a lot.

There is another reason besides financial to want better MPGs.
Fueling up while towing especially in an area one is not familiar with is a pain. For some reason the fuel tanks in the gas trucks are the same size as the diesels. So making the switch increases the range a lot.

Frankly, if he's already getting 6.9 towing with his present truck, a Cummins diesel isn't going to get but about 8 - 10 mpg at best with that fifth wheel. I agree that getting a diesel doesn't make much sense. And then there's also the price disparity between gas and diesel fuel. Presently, diesel fuel is $2.59 here and gas is $1.99. Before the pandemic hit, the price difference between diesel and gas was .20 to .50 difference extra for diesel so that absorbs the fuel savings substantially. DEF isn't a huge factor as it's pretty inexpensive at Wal-Mart. The only reason to trade for a diesel would be for the improved pulling power.

Ford warrantys to 100,000 on the drive train. There is a diesel fuel card available to any diesel driver (TSD for net serch) and I paid $1.19 during the pandemic. Prices are on the rise and the last fill was $1.63 so how are you saving?? BTY my 2015 F350 stock 6.7 pulling 14K get 11+ towing. The newer are supposedly better yet.
