Where to sell RV items other than craigslist?

I have sold lots of things on Craigslist but you need to use common sense. Although I had them come to the house, it was never when I was alone and no one ever came into the house and few even saw the inside of my garage.

Other than Craigslist, the free papers some have mentioned, posting on bulletin board at the grocery store or Laundromat are other options.
