My Nissan Titan had rear A/C vents and heated seat for the rear passengers. My wife's 2016 Tahoe has good hvac and other basic amenities that I just assumed the 2018 Silverado would have so I didn't think to look. It's my own fault for assuming things, but the fact is, putting up with a hot truck would have made the growing list of things to cause people to bypass the Chevy Silverado.
