Nice inheritance! I didn't realize there was much maple syrup boiled in NC.
Mapletrader.com and
sugarbush.info are two maple forums that have classified sections. You might get an idea of value in there. Or search the Vermont Craigslist or other syrup producing states to see if other folks are selling similar rigs.
I think people use syrup evaporators for sorghum or molasses so maybe there's a market to your south as well.
