Factory photo of 1 of RVFD's 1966 Mack B-models that were of a different body style than the previous deliveries. They were 750/500 and most lasted into the 1980's. Perhaps Cosgrove has some stories of riding tailboard on these... <img src='http://www.firepics.net/groupboards/public/style_emoticons/<#EMO_DIR#>/hysterical.gif' class='bbc_emoticon' alt='
