The Stovebolt you are referencing that Kevin Costner and his wife rode around in at their wedding, does in fact, belong to his wife's father. She thought it would be novel if she rode to the wedding, at their country hideaway, in her father's truck, which he was driving. He escorted her to the wedding, much like a father would do in giving the bride away at the wedding ceremony. I caught a glimpse of the truck on one of the entertainment news channels highlighting celebrity weddings. I believe their farm is somewhere in Montana, if my memory serves me correctly. Supposedly, her father is an "old truck" enthusiast.
