"I've been doing good with my sobriety," he told The Sun. "[August 19] was three years since I've been completely clean."
"I don't really go to meetings or anything," he said of his recovery. "We've just got so much s--- going on and I feel like when I go to a meeting everybody just wants to talk about the show."
Following years of rehab and jail stints for his substance abuse, the reality vet said "working with metal and building race cars" now has helped him keep busy and maintain his sobriety.
His wife, Mackenzie, added that the the couple are doing well, despite some setbacks. "We are in a happy place at the moment.," she explained. "Nobody is saying that we haven't made mistakes, because we have. But I'm not going to harp over them or live in sadness or shame over the past five years."
