I also got a text at 3:58 am from this number.  I am in PA.  So when I get responses from my Craigslist adds at odd hours from my local listings I check online before responding.  Well, I found a great Youtube post that someone made about this scammer.  It is great!  So I responded to this scammer with the address of the Youtube post with a bit of poking fun at him/her.  What do you know?  I got no response!  I guess they aren't all that interested in the sound system I have for sale anymore, hum......
