I had both diesel and gas HD trucks. A 2016 F350 6.7L PSD. Great truck, not great on fuel but better than gas. Ford told me I had to run a additive in it every fuel up, that was a pain to always have and add. I also had to carry DEF because it went through so much when hauling a 9,000 lb holiday trailer. I loved the truck but the maintenance was expensive and the diesel prices in Canada are higher than gas so it didn't pay off in the long run. It also went through tires faster than the gasser because of all the fun torque.
I now have a 2018 Power Wagon and I love it. I think I've had 7 recalls and 2 warranty items. Way more than the F350. The fuel milage is about 4 MPG worse on the highway and 6 MPG worse towing. No additives needed in the fuel or changing the fuel filters every second oil change, although oil changes aren't cheap. They use the same oil as the SRT engines. It tows the holiday trailer fine but you do notice the huge difference in torque, but it still does well. Just way more RPM's. For me the gas is a better fit and I'm happy with it so far. Lots of people use diesel for overloading and love them. Delete them and get some reliability and performance back. They are expensive to fix though.
