I'd guess my net environmental impact is just now lower than US average because, despite my fuel consumption when moving my home, it's tiny, energy independent, and it doesn't move far or frequently. I don't really know. I just don't want to be judged unfairly, particularly when seeking help trying to do it even better.
I want to downsize my truck for cost and fuel efficiency. I've had this truck, my first, for a year, 3.5k miles. I've towed the trailer a short thousand miles without incident and including city, highway, and interstate.
Current setup:
'19 Chevy 2500 6.0L 4WD
Hitch towing ~2.5 tons GVWR (14', enclosed, tandem, brakes)
Getting 8mpg @ 70-75mph
Next truck budget is $10-20k. I'll keep it probably until the frame rots. I'm planning on replacing shocks & wearable steering components, am not averse to some work.
Should I target a 1/2 ton gas (leaning Ford 5.0L 4WD), a different 3/4 ton gas (which and why), or a 3/4 ton diesel (leaning Dodge Cummins)?
The paper numbers say I should get a 1/2 ton gas. But, my more experienced friend thinks I'll be a lot happier spending more for a diesel because diesel engines can last a long time, it'll at least double my fuel efficiency, and it's a little extra overkill for an easier tow.
I'm open to all informed perspectives. What's my best plan and why?
Edit: I kept the Chevy 2500 6.0L because the local market didn't support transition on the sale side. I also bought a '98 Dodge Cummins 12v diesel that needs work. It'll eventually replace the other truck.
More tires?
Yes.
Diesel engines are heavy, usually being cast iron blocks to support the continuous high torque & high temperatures caused by towing and their very high compression ratios. This heavier weight on the steer tires wears tires and brakes faster. Gas trucks almost all have aluminum blocks now and are much lighter. This makes diesels usually require tires that are 1-2 letter load ratings higher than a gas truck, which is also additionally more expensive to buy.
Diesel engines also produce significantly more torque, and torque is what causes tire wear during acceleration if you beat on it or tow a lot (it's a huge problem with EV's right now).
OP here: I've an ME Auto degree. I never thought of increased tire wear. It makes perfect sense. Great explanation. Thank you.
Yup. My dad's F550 haul truck goes through steer tires about every 15k miles. The alignment's fine, it's just SO MUCH weight on the front having a full size 7.3L plus the commercial chassis frame that they wear quickly from fighting the road crown with a trailer behind.
