I’m looking to buy a used pop-up camper in one of two brands – Chalet and Aliner. I was spending a lot of time doing internet searches for used ones until I found these two sites. I recommend them for anybody looking to buy a specific used item. Real time savers.

This site gathers all relevant listings from Craig’s List sites across the US – maybe some other classified sites as well. The link I just gave you is for an RV but, as you’ll see, you can search in other categories from the list on the left of that page.
http://www.oodle.com/ This site looks a a list of classified in a number of categories. You can ask them to e-mail you whenever they find a new listing on the products you seek.
The results of using just these two sites seem to be doing me as much good as searches using a large number of other sites. I may be missing some listings, but it does not seem to me that I am missing a lot of what I found before using far more sites and time.
