When I built my 2024 Yukon Denali the 3.0 Duramax option was $1,500 cheaper than the 6.2 gas engine. My wife's 2025 Tahoe has the 6.2 gas which is a nice motor. My Yukon averages 24 mpg combined, her Tahoe averages 16.5 mpg combined. My Yukon is my backup tow vehicle for my 2 smaller trailers. The other option is the 5.3 which was not an option I would consider.My thoughts would be, what does the 3.0 Duramax offer as advantages for its upcharge? It does have about 100 ft/lbs more torque, but from what I've seen, it's only available in pretty high trim models. Basically, making the 3.0DM require a $60k plus truck.
Do you need the extra 115 or so FT/lbs? They are both rated to tow the same. The 3.0 doesn't make it a 5/8 ton truck in capability
In the Sierra 1500 the 3.0 is $2,110 cheaper than the 6.2.
