Purely from the research point of view, it was listed as a one owner (personal vehicle) at carfax report with a Carfax buy back guarantee.

If you've looked at new prices for Rams, it's an OK price, but about what you'd expect given their relatively low prices for new ones in their basic model categories. I don't know about the miles but considering it has a fifth wheel hitch in the bed, it was pulling something part of the time at least.
