Scam on Craigslist

I am trying to buy a used travel trailer on Craigslist and twice different people (or so they say) have listed local trailers for sale for $1,200. When contacted they are not actually local, but instead live 1000s of miles away. But they claim they are selling it through E-Bay and they will deliver it to me free and I have five days to inspect it. This is the second one of these I have had. I did not by either, of course, but this clearly is a scam
