If I can be so bold - here is something else to try... Don't bother with Craigslist's homepage.
Go to google and type in the following:
"site:craigslist.org camper scamp trailer -wanted -wtb
You have just told google to search all of craigslist for the words camper, scamp
, and trailer, and not to return any listings with the words wanted, or wtb (want to buy). You can narrow down the search further by noting which craigslist cities you wish to search for. If you, like me are from Canada, you can limit the search to Canadian listings by putting "site:craigslist.ca" on there instead. Maybe you want to limit it to the Toronto Craigslist? "site:toronto.en.craigslist.ca" will do it. Sadly you can't limit it to province/state. If you want ot search in french, then try: "site:toronto.fr.craigslist.ca"
On the downside you would miss an ad like this since the minus sign told google to skip anything with the word "wanted" in it:
"13 foot Scamp
for sale in perfect condition with solid gold faucets and diamond encrusted door handles. Wife wanted
something more girly. $150"
you can do the same search with ebay, etc, all right out of the Google search window.
