Rolling, wha' part of SC ye in? I had an old 10'x50' mobile home on our place that we lived while our house was built back in 1980. Different people lived in it over the years, but county taxed it too high. We could not give the thing away! Craigslist to sell, nope. I finally found a man in South Carolina (me place is near Augusta) who came and dismantled all but the frame, which he left. I finally cut it up with a saws all which cut it no problem, sold scrap iron for $250.00. Around our area of wha's called the CSRA, ye canno' give trailers, aka, mobile houses away.
I think if ye have the time, ye're just going to have to bite ye Olde bullet and tear all that mess down. Can ye burn on the land? Ye'll need to have a good burn pile, or trailer to haul mess to local dump. Let us know how it goes.
