I'm guessing you got a FWD and not AWD? It looks like the trailering stuff includes a stronger alternator, too.

If you have an RS with AWD I think it comes standard with the tow package. Does your vehicle have the built in receiver and 7-pin wiring? I think the thing about the alternator I saw on the "build your own" part of the Chevy website when I was playing around with it. It's in the info for adding the tow package. If you download the Blazer brochure there is also info about towing/trailering specs where it compares models.

Look on page 15 of this brochure. Under Mechanical it says "Includes Trailering Equipment" for AWD models and under Cooling System it says "Heavy duty (included on AWD models;...).

Also, if you use the compare trims tool on the website and compare RS AWD and RS FWD you can see the FWD comes with a 155amp alternator and the AWD comes with a 170amp. It also confirms what I saw in the brochure that AWD comes with heavy duty cooling, hitch guidance, and hitch view.
