what to do with left over remodel items?

I've done several upgrades since I've been full time and I usually do the work in one of the smaller 'mom-n-pop' parks. I usually discuss disposal of my old items with the owner/manager prior to beginning the work. I've replaced carpet, a jack-knife couch, an older style leather chair, a small cabinet, mattress and 2 tube type TV's so far... and everything but the TV's have been taken away by either other RVers or locals who wanted/needed them. While I may have been able to get a few bucks for some of the items it wasn't worth the effort to advertise anywhere and hang out until they sold. As your still in a home you might want to try and sell them... or just put em out on the street and if they are worth anything, someone will claim them.
