Don't know if you guys have ever surfed this link, but all the trailer posts made me look at this again. The link is: http://www.firstgov.gov/shopping/cars/cars.shtml The two I look at quite often are "GSA AUCTIONS" and "SALE OF SURPLUS PROPERTY FROM THE DEPARTMENT OF DEFENSE". WIth the impending base closures in the US over the next few years alot of equipment goes through these pages. In particular the second one I list above. You can search by state or by item etc. Just did a search for trailers and there are quite a few in there, though none up in the Northeast. 
Happy Hunting!
