How can I get an old RV camper (not worth anything) hauled out of my yard in Ocean County, NJ?

Other answer:

Call a scrap yard. Search craigslist for guys who do recycling or post an ad for a free rv for scrap
Places like "Got Junk" will take it to the dump – it will cost you – they basically come in with a couple of sawzalls, cut it into pieces and cart it to the landfill.
I already had a junk dealer say he'd charge me $650 to cut it up & haul it out. Not happening.
If it really is worth nothing ( & no owner you can charge removal to) then you' either pay someone t ocut it up & cart it or you do the work yourself.
