You know, I've seen a lot of Ric's Corner videos and I can't recall him mentioning Lou. Ken Waller, Draper, etc. pretty much all of the Venice crew often, but not Lou. Which is weird since Ric was on the Hulk. I could have missed it though.
There's a fair number of stories about Ric and Ferrigno hanging out here and there, but he was never on the show. -

Ric sorta (unintentionally?) throws some shade at Ferrigno here -
“Lou is a good guy. I’ve known Lou forever. He’s just the nicest, warmest, friendliest person to me. I have a lot of respect for him and when I worked on the show, I had no idea where it was gonna go…So they made me the middle Hulk, which had it’s own following. Working on the show was fine. It’s like working on any movie. You sit on the set and you’re bored to death…Lou and I would sit in this trailer and have lunch and all he would talk about is, what do you think Arnold’s doing, what do you think Arnold’s training? I said, ‘Why are you so worried about Arnold? You’ve got this series going. You’re making a fortune and you’re doing well. Don’t worry about Arnold.’ But he was always concerned about what Arnold was doing at the gym when he wasn’t there. Then he wanted to fly a helicopter, have a helicopter take us to workout that night. You know, it’s not that important. I’m tired. I’m going home.”
