Hi all, following the build of my new 2023 Ram 1500 Big Horn and have been able to see the equipment listing and see the 2 Customer Preferred Packages 27Z and 2TZ. I have searched the internet and can only find reference to the 27Z possibly referring to the 5.7 Hemi upgrade (not sure if correct) And I cant find anything on the 2TZ. If any of you might know what they are I would appreciate the info. If I find out when truck is delivered to dealer I will let you all know. Thanks I'm excited to pick it up says anticipated March 8, 2023
