| Anybody towing with the newer GMC 2.7L TurboMax engine? I have a Ranger 690 with a single axel trailer. Everything falls well within the stated towing capabilities - and every salesman I have talked with (of course) says the engine will pull like a dream in their new 1500s.
Anyone currently doing it and liking it? |

| We just got a 2023 Silverado Trail Boss with the 2.7HO and towed my 1850 Skeeter WX single axle and could not even tell I was towing anything for the 700 miles. Says I can tow 9000lbs and I weighed by rig with gear and half tank gas and was at 5200 #.

Location: Cedarburg, WI. | I pull a 1750 Fishhawk with a 2021 GMC with the 3.0L duramax which has very similar hp and torque specs as the new 2.7HO. Mine pulls great i bet you'll have no issues. |

Location: SE, WI. | I’ve talked with a couple salesman about these turbos, and HO’s. They told me the construction guys and landscapers are having No problems with trucks doing their jobs…. My next question was, “ what’s the longevity of these new Turbos engines?. Salesman smirked and Said; that remains to be Seen! I’m Going to continue to Run my 5.7/ V-8’s and wait till there is some concrete evidence of Longevity of these smaller turbo engines…. |

| For almost 30 years, I drove a GM product with the V-8. Today I picked up a new Tahoe with the 3.0L Duramax. Only time will tell whether it was the right move but talked to 2 pick up owners with the engine, both of whom had the V-8 in other GM trucks and they really like the Duramax. Amazes me that they can pull 495 pounds of torque out of 3 liter motor, at less than 1,400 rpm. |

| I’ve owned new GM trucks for over 20 years, I got the same salesman line when I bought my 2023 …ah no thanks!…I’m still a firm believer…” No replacement for displacement”, when GM takes the 6.2 liter and throws a few bells and whistles on it it’s a 650hp and 650 ftlb of torque beast… the 6.2 and 5.3 have proved to be ultra reliable, I’ll stick with V-8’s for as long as I can get them |

The 6.2 is actually the standard engine in the trim line I bought. Aside from concern about mileage, they recommend you use premium gas in the 6.2. Not only expensive but not always available at every station. Great motor, power to spare. If I was towing a big fifth wheel, my choice might have been different. |

| Not the exact same but have the Ford 2.7 since 2018 and used to tow a ranger 690 and now tow a similar sized boat. Have towed from Ohio to Wisconsin, Minnesota, Ontario, Quebec without any issues. My buddy has a high end GMC with their small diesel, tows a larger camper no problem. The smaller motors seem to be doing really well in my opinion. The Ford 2.7 has way more HP and torque than the old 5.4 V8 and at a lower rpm. You get the benefit of the power and better mpg especially when not towing.
To me it's not the motors or transmissions it's more so these vehicles just don't seem to last related to all the "tech" hooked to them. Example I've had 3 codes pull up in the last year one putting me in limp mode. Everytime, once the truck is restarted they don't occur again. My buddies high dollar GMC once wouldn't start leaving him stranded the first year he owned it and has been in the shop twice for check engine lights and not running right that were related to known issues fixed under warranty. These newer trucks are very nice, I have faith in the motors and transmissions doing their jobs I more so worry about these nagging issues that really hurts reliability related to all the sensors and tech making them run. Feels like once you get to 100k you are already thinking about needing to replace the vehicle. |

Location: Cedarburg, WI. | As long as they build the lower end of the motor heavy enough and can keep it cool i see no issue with the newer smaller engines. To me lower rpms = longer life.
Plus as others have mentioned when towing at freeway speeds and rpm's the newer smaller engines have almost double the torque while moving. My lil 3.0L duramax don't even think about coming out of overdrive like our 2017 GMC with the 5.3L did. |

Riding with my brother-in-law in Sawyer County last year, noticed that pulling up a long hill in his crew cab Silverado with the 3.0 Duramax the rpms did not change. My Yukon with a 5.3 would for sure have shifted down on that long uphill. |

Nice to make all the torque down low where you need it. Also the 10spd transmission helps 
Only thing that would keep me away from the 3.0 Duramax is the belt that drives the oil pump and the fact that it runs a CP4 injection pump. Also, if all you're running is US fuel, I'd definitely be adding a bit of BioD to increase lubricity. US diesel has some of the worst SCAR ratings out there.

Thanks for the tip. Don't know of any BioD near me, but maybe one of the additives would be a good investment. Chevy does provide a 5 yr/100,000 warranty on the Duramax 3.0L so if there is a problem, should be covered. |

| Any additive to help lubricity is fine. BioD is just super cheap and does the job well |
