These "old guys" are in the same boat as a lot of us. What's gonna happen to it all?
Like Patrick, Jim Carter loves to talk trucks. I know neither wants their business to just drop dead with them. I would imagine it is hard to find someone who is interested in the TRUCKS, not just the business end of things (a/k/a making money).
I know Mongo is that kind of guy and he's super busy -- he needs to be cloned. Same with Tony Smith - loves the trucks -- but there is so much work and it just keeps getting bigger.
