I have bought a 2024 blazer without the tow package. Unfortunately now I'm wanting to add it. Any suggestions? Thanks in advance.

 

I'm not an expert on the new Blazers, but I'd think the dealer might have the best info on what it would and cost to retrofit one. The sales and/or your owners manual will have the detsils of what the towing package includes, e.g., hitch, extra transmission cooler, wiring connector, etc. You also can likely find information at eTrailer.com.
