I often wonder whom is thinking this up. Part wrote to Charlotte NC, more or less directly South of us, five or six hours. Ideally with all the dealers along the I-81 corridor a truck would run North dropping off parts but that is reasonable thinking. I always assumed it went up to the Martinsburg W VA warehouse only to eventually come back down.
Tracked it this morning, trip plan is take it to the Michigan cross dock, then back down to Martinsburg. I cannot make this stuff up
