Am I wrong here?

I've gotta disagree with the other replies. If you were 1st in line, then the seller should have told all others where they were in line. They can still look at the trailer and even make an offer, but any decision can wait until you had a chance to look at it and make an offer.
The seller is then free to select the best offer.
Just the way I do business.

How do you know he was first in line? I don't see that mentioned any where...

I have to agree...with the yahoos that craigslist and the likes breed, money talks. First on the scene, with the green.
