Hi everyone I’m a newcomer here decided to join as I just bought a 2020 Chevy 2500 lt z71, ccsb with the l8t. We love the truck more than we thought we would, huge improvement over the 6.0, which IMO had very few flaws, never owned one but many family members and friends have and I have driven many. I see a lot of people complaining about the 3:73s on here, I’m assuming these people haven’t driven one, our truck averages 14.5 all around and the wife had it getting 16.5 on a 50 mile stretch of 2 lane cruising around 55. This is great mileage for the size and power of these trucks. Only towing iv done so far is my father in laws 10k lb Kubota excavator and I was extremely impressed for a gas powered truck, no complaints. Trip was only about 15 miles on hilly backroads, no highway towing yet but I will share my experience with it as it comes. As for everyone saying that ford is outdoing gm in the drivetrain department, I have yet to see a ford truck that is as trouble free and long lasting as the gm trucks with the 6 liter were. And I know a lot of ford owners and I drive one for a work vehicle. Hopefully the 6.0 reliability caries over in the l8t. So overall extremely happy with our new truck. As I said I’m a newcomer here and I’m also the happy owner of many 99-06 gen 5.3 vehicles, a truck, a Yukon, and a burb. I have quite a bit of experience working on these and would be happy to help anyone looking for advice.
