In some states they now print out titles while you wait. You go in, hand them your paperwork, pay, and they hand you a freshly printed title.
I can't recall if there is a purchase date on it or not. There may be an issuing date, but then I suppose the seller could say that when he went to put the trailer on the market he couldn't find the title and had to get a duplicate (new) one.... What's one more fib?
PS: Kevin, I agree that there's nothing really wrong with "flipping" (i.e. re-selling) a trailer. A person who intends to do so takes a calculated risk, much like buying and selling stocks. But I agree with you that the blatant lying (on both ends!) is really, really wrong.
(I can also see where "flipping" strikes a nerve with some people. Even though I logically don't think it's wrong, I have a bit of the same feeling. Maybe it's because many of us love these trailers a bit more than "just" inanimate objects, and so it almost feels like selling pets or something. I tend to buy high and sell low, though, so what do I know
