Let me clarify: The Craigslist ad is unusable, because their for sale
ads don't last ten months.
On the FGRV archives, I think they are only for known "sold" campers. Presumably James T never reported back that his trailer was sold, so the ad would not have been moved. That seems reasonable to me, as the moderators are volunteers, so I wouldn't expect them to try to contact all sellers to see if their trailers have sold or not.
However since James T only made this one post, and has not been back to visit the forum since January 31, 2010, he probably won't see your response (you can see this by looking at his profile statistics, if you'd like).
I see where perhaps my initial response was confusing; I didn't know if you realized you were responding to such an old ad. I guess I could have been clearer.
Good luck in your trailer hunt. These little guys typically sell pretty quickly (although of course not always).
