Some thoughts about the gas vs. diesel debate:
1. Its your truck. Not a random forum guy's, or your uncle's, or your best friend's.
2. The diesel truck is extremely capable.
3. The gas truck can do 90% of what the diesel truck can do.
4. If your weekends are spent racing your buddy up mountains with a trailer in tow, the diesel is the only choice.
5. Diesel has increased maintenance, the fuel price is higher, and you will have to drive thousands of miles to make up for the price difference, if you ever do, even accounting for the resale value.
6. Diesel 2500's have half ton-ish payload capability.
My experience, for what its worth:
My Ram 2500 is my 7th pickup. I have had everything but a Ford.
I have a 2020 Laramie 4x4 with the 6.4 and 3,150 pound payload and it is perfect for me. The price is right, plenty of payload, hauls anything I need to haul, and the coil spring rear is smooth.
This truck rides just about as nice as the 2017 Tundra it replaced, gets 10% worse gas mileage (and I have the 4.10's for my future 37" tires), and adds 1800 pounds of payload.
I had a 2006 Cummins 3500. The torque was great but my trailer was much heavier back then. Diesel maintenance and availability was only slightly annoying but concrete freeway expansion joints were my worst enemy.
This truck can pull my 6,400 Lance Trailer practically up a vertical wall with 6 people in the cab, camping gear in the bed, and enough leftover capacity for 20 bags of concrete. I love this beast.
I say get what you want. But don't let anybody tell you that the gas trucks suck. They do not.
