When members of the trucking industry gathered in Lancaster, Pennsylvania last month for the annual Mother’s Day Convoy to benefit Make-A-Wish, just about every type of working truck imaginable was in the ranks. Many were all but brand new and decorated with a stylish theme. Others were loaded and simply taking time out from making a delivery to participate in the 30th annual event. Among the nearly 600 trucks in the convoy were several COEs that were still hard at work despite their advancing years.
