I’ve ran the 7.3 with 15k pounds, it’s not my 6.7psd but it’s pretty impressive, torque is in the right RPM range for it. Best big gas on the market, for now.
I have yet to own a DEF equipped truck to have a DEF pump or heater make it 75k. I’m on third on current truck. Since 2010 I’ve been through 6. Do the math. It’s ridiculous. I also yet to have 2010 plus truck to get more then 14-15 MPG
For a 3/4 ton I agree but that 7.3 has had big issues from what I remember, the 6.2 I had in my 2019 f250 was as reliable as they come with a whooping 11.9mpg avg for my driving and 7mpg towing lite. I really didn’t need a 3/4ton so downsized to the GMC 1/2ton, I get 22mpg in town and have had up to 34mpg hwy unloaded. Towing the same loads i did with my 3/4ton I get 15mpg.
The gravel yard loaded up my dump trailer a little heavy recently and that little diesel pulled the 12k load no problem up my steep road, wouldn’t recommend it as it’s hard on stuff but for 2022 GM bumped the towing to close to 13k so maybe not as hard as I thought on my 21.
I have a warranty, It’s there for stuff that goes wrong, seems everyone assumes they will not have any issues with gas vehicles, guess how much you’ll pay to fix a diesel or gas under warranty, $0.
Another thing no one discusses, no matter if 1/2ton or 3/4ton, the diesels have a 5yr 100k warranty while the gas has a 5 year 60k, pretty easy to see which warranty will be gone sooner if you drive much.
Oh and on the 1/2ton diesels for GM, it costs $900 more then the 5.3 and is around $1700 cheaper then the gas 6.2 GM offers, which they highly recommend you use premium fuel for.
Truthfully if towing less then 9k, the 1/2ton diesel is the way to go, if over a 3/4ton diesel in my view.
I hated driving my 3/4ton gas Ford in the mountains wrapped out at 5500rpm+, same load and my little diesel pulls it up the mountains no issue at half the rpm.
If GM would put the little diesel in a 3/4ton I’d buy one, you’d get better mileage, just the weight of the truck would help work the motor and you’d have the same pulling power, if not more, as an early 2000’s 3/4ton plus the added weight of the vehicle for towing stability, I don’t need an 800hp 1200ft/lb vehicle.
