Yeah with the Duramax 6.6 and Allison transmission. I love it. This one is a 2015.5 and my previous was a 2007. Longest I've ever kept a vehicle. I'm thinking about a 2018 when then come out but they discontinued the iridium paint job which is sad. I love how it looks purple, then black, then grey, etc. so I may just hold into this one for a while longer.Denali HD?
