Located in Liberty, Maine, JWD Premium Products was started by Wayne, Susan and Jeremy Dieffenbacher as a retail hobby business in 1992. The manufacturing division began operations in 2005, producing "EasyFit" loads, designed to fit specific cars right out of the package. The selection includes coal, iron ore, scrap steel, taconite, ballast, gravel, talus, blasting rubble and woodchips. All loads are accurately colored and many have hand-painted detail.
