I am thinking about upgrading my 2004 Chevy Silverado 2wd with over 250,000 miles to 2018 LTZ Z71 fully loaded for variety of reasons. Getting a really good deal. It is 5.3 liter V8, not pulling anything super heavy and have test driven one and like it. So opinion, any issues you have had if you own a 2018 or even 2017 as basically same truck, I am interested. Been Chevy all my life and at 55 not really looking to change.
