According to my mother, who was friends with one of Dan’s distant relatives, he was also a very nice and kind person. Her friend told her that when Dan found out his TV broke, he bought him a new TV and then drove several hundred miles to his house to give it to him.
Of course he was nice and kind, he was from Texas.
I read an article about him many, many years ago that mentioned that after his acting career progressed, he was considered by his peers the most liked person in Hollywood. That natural kind and warm personality of his sure came through when he played Hoss also didn’t it?
