I have the 2023 3.0 baby diesel and haven't had any issues though I've only towed 10,000 Gross. My 2019 Sierra with the 5.3 and 8 speed pulled ok, but mileage and torque sucked. Plus the transmission was crap. I went with the diesel to try something new. I'm satisfied with it. Now if the price of diesel would come down. My neighbor has a 2024 Sierra 1500 with the 5.3 and swears by it. He tows a landscape trailer everyday with two zero turn commercial mowers two push mowers plush other equipment. He does say the gas mileage isn't great but has had no issues. Another friend has a 2023 2500 with the 6.2. He runs a transport business hauling small loads on a twin axle heavy trailer. He has had some engine problems but nothing serious. He is considering going to a 2500 diesel for better mileage and higher torque. Depending on frequency, weight and terrain, I wouldn't have any problem with the baby diesel and max tow kit. Keep in mind, the max payload is 2400lbs. Gross is around 13,000.
