Just went through this decision. I was looking at a 2020 6.4 and a 2020 Cummins. The gas had more bells and whistles than the diesel and rode really nice. Price was a little cheaper too, both are used vehicles. Did a lot of research about pulling our 10k trailer with something (four wheeler or golfcart) always in the bed. The diesel just made more sense. I've pulled with a Ford V10 and their 6.2. The V10 was a great engine, just thirsty. 6.2 even with 4.30's in it is way underpowered. The Cummins powered truck does have fewer bells and whistles, but runs good and pulls like a dream.
