May I suggest that referrals be used sparingly?
There is already www.fiberglass-rv-4sale.com
that reposts pretty much all the legitimate Craigslist ads and filters out scams. For those wanting to get a jump on new ads and willing to do their own filtering, there is www.searchtempest.com
In my view it’s best to limit referrals to trailers that are not listed on a major classified site, rare or unusual units of general interest, and cases involving personal knowledge of trailer or seller. Referrals clog the list of new postings and detract from direct listings on this site.
