Been a big diesel fan forever! Still am and I don't see that changing. Contemplated a Duraburb conversion, but my longing for a diesel conversion is bigger than my wallet. However, my 2018 Denali is about as perfect of a gasser vehicle as we have owned. Features, utility, towing, you name it, it just works for our family. So how can you make something perfect for us work better? Throw in a GM 3.0L diesel! I know these 6.2l gassers will run 200K+ miles. 10-speed should too, but the jury is still out on longevity because it just hasn't been around long enough. And I plan to run the drivetrain till she's tired or broke. Since it works so well for our family, I'm wondering if GM will offer a "plug and play" diesel drivetrain option. Anyone hear if GM will offer the 3.0L as a crate engine like they do for their other engine/tranny options? https://www.chevrolet.com/performance/connect-cruise-powertrain-systems
