Growing up in Massachusetts in never saw a dirty UPS Package Truck. The closest center was in Shrewsbury and from what I was told every truck was washed everyday. I now live in Maine and the center I work at does not have a car wash. When I first started back in 2007, the local sort would hand wash the trucks every night. Nowadays, I can't recall the last time I saw a clean truck. In addition to a pile of trash and dirt inside the trucks, there's probably 10 lbs of dirt on the outside. It's almost embarassing! Is this common elsewhere?
