Yeah, I am seriously considering a new Tahoe Z71 too and have been exploring different build specs on the Chevy site for over a week now. Even up to a couple of days ago, I got excited about seeing the new Shadow Gray availability for the 2019 Z71. But yesterday I noticed the Z71 package disappeared except for the Midnight Edition package; even then, no Z71 badging on the outside, lower bumper, and you have to stay with black!
This may be a deal killer for me coming back to Chevy as I wanted a Z71 as I could rely less on aftermarket and still not get eveything I want (i.e., hill descent control); I actually take my trucks off-road so need the capabiltiy. Plus, I just prefer the Z71 packaging over the LT. Maybe they are just working the website because they are going to be offering the 6.2L in the Z71 package soon! Okay, I can dream...lol.
But I am going to be bummed if Chevy just cancelled the Z71 on the Tahoe for 2019 as my old 2004 Z71 was one of my favorite vehicles ever (and I have had a few). If they did, I am outta here Chevy!
