I had the 2024 GMC 2500 AT4X and now have the 2025 GMC 2500 AT4X both with the 6.6 gas. No issues with plugs or oil in either.

My buddy just got a new GMC Denali EV. What a truck! Crazy fast. Super range empty (700kms). Crappy when pulling a big trailer though. He pulled his big pontoon from Stratford to North Bay and had to charge 2x on the way up and ended up having his BIL with a gas Yukon tow it home.

I think the tax man would be after you Strong Farmer, Dyded fuel is for off road use only, your tractor is exempt for road travel, all others are not.

True but if that internal combustion engine is only running a fraction of the time that is the savings. How much heat gets pushed out the tailpipe and rad in an internal combustion engine. Also its a small naturally aspirated 6 cylinder motor (presumably de-tuned for efficiency and reliability). No turbos to crap out and 2 cylinders less than a v8. You get the benefits of electric (torque, instant power, quiet, etc) without the range anxiety. Diesel electric is not new tech. Been used in rail and mining for decades successfully. Time will tell, but I think this idea has merit.

Ya around there, my best was 13L per 100 it gets cut in half at a minimum when towing heavy, but man does it ever tow nice!

Ya, my 6.4 in the dodge ain’t winning no fuel mileage competitions, but what is in a 3/4 ton truck. It’s pretty crazy the difference between a 1/2 truck and a HD truck.

I need a 3/4 ton for work. But I have decided to keep my 6.0L I know a guy that has one of those 3.0L diesel’s and it’s phenomenal on fuel. I wish I could say the same about my truck lol

Just an FYI. If you dont need a HD. Buy the baby duramax. Mine is phenomenal with fuel consumption (better than most cars) and It will pull a hell of a lot
