Welcome ! Once you go diesel you never go back ,
the only issue with the 2017 is emissions junk, DEF and DPF which must be deleted ASAP
most guys like to ride out their warranty until it is getting ready to expire, but in all reality if the truck does have issues it most likely is because of the emissions restrictions. So catch 22 I guess
I used to live in Westminster/Arvada/Colorado I currently live in Louisiana been back here about six years because most of my family is here but I will be moving back to CO next year, getting my Duramax ready for the mountains as we speak
