Rumor has it GM will raise the tow rating for the oil burner (gears & radiator?) to over 10klbs in 2021


Ya I've read that too.  Heat is the enemy right now as the DPF sits under the hood on these.  The exhaust outlet makes a 180 out the turbocharger and goes straight to the DPF that sits right under it.  It was done to improve DPF operation and get the exhaust hot and more optimized faster but adds to engine bay heat.  Interesting fact, in the 2019 order guide there was a "Diesel Off Road Package" that got 3.73 gearing and Duratracs.  Never made it for 2020.  I think if they can just bring NHT Max Trailering to it with 3.42 gearing and stronger engine bay cooling, they could get 11-12k out of this truck.
