.... googled 'charitable donation changes 2018' and came up with

so, is best to inspect your tax situation because the rules have been changed.
To get it hauled or driven away, to get rid of it and get it the heck off your property, there's the 'free stuff' section in the 'for sale' heading of craigslist-nh where you can post photos and let someone have it for free. Hot tubs, sofas, recliners, and old 42' sailboats seem to be common items in the 'free stuff' section, so it seems like a new home can be found for a 39' rv.
How's 'bout the suggestion to re-purpose the 39' rv into a cozy, comfy, air-bnb daily tourist rental ..... with utilities, water-sewer-elec-wifi-tv off to the side on your resdential waterfront property as a money maker to help with the prop tax bill ..... makes me think about Randy Quaid's character .... Cousin Eddy .... in the 1989 movie 'Christmas Holiday' ...... going air-bnb with an rv could be some type of curious adventure! Maybe include an old hot tub from the free stuff to go with the old rv as a sought after rental amenity?
