I know it's a little old, but I found this thread trying to find out more about the ERIP myself so I thought I'd share what little I know so far.
There are a few dealerships that are actually advertising this program on their web sites., just Google "Emergency Responder Incentive Program"
I like this one because it actually give a general idea of the discount.
As the site says it's not widely known. I have talked to a couple local dealers and they knew nothing about itincluding the salesman I talked to at the dealership where I bought my current RAM. I'm going to try and talk to the sales manager there about it and see what he says.
As a back-up plan I have found two dealers via searching for the ERIP that are only about 3 hours from me - I'll contact one of them.
