ColoradoChevyGuy, I feel lucky if waiting 15 months for a truck could ever be considered lucky. But when I did finally take delivery of my truck the only thing missing is the park assist and I don’t find that a big deal. My front and rear cameras go live when I put it in reverse and switch from front to rear as I shift forward and reverse. Not sure how much more I could need. Not ever having park assist I do not know what I am missing. Perhaps distance indicators? Not sure, if anyone here knows could you enlighten me? I figure it will be late fall or even next year before I see the retro but that’s ok with all things considered. I find the truck more and more fun to drive every time I go out with it. I have the 3.0 and with the 10 speed transmission it is so smooth it isn’t funny. So far with nearly 7000 miles my average MPG is 30, nothing to complain about there.
