this number is posted in a craigslist ad in alaska for a travel trailer- they text back asking for email adress to send additional details to- this is a connecticut number and they text back from an omaha number: 1-402-500-2217... it's looking a lot like spam/scam/phishing

Same here.  They emailed back with more info on the camper, but my spidey senses spiked when I read it.  Grammer isn't completely right and some of the photos are stock photos from the factory.
