I just verified with Roadmaster that you will need to use a charge line kit when flat towing your 2019 Chevy Blazer. To do this you will want the Roadmaster Battery Charge Line Kit for Towed Vehicles item # RM-156-25. Once you install this kit you won't have a dead battery again. Don't listen to the GM dealer.

I have linked an installation video below for you to check out. This is a universal fit kit so the video being on a different model Chevy won't change the installation method.
