This is where the difference between years gets interesting. On my '82 all the controls are mechanical. Now that the original cruise control is gone, the only thing vacuum operated is the step. I have no tank, the hose goes directly from the vacuum pump to the step. You guys with newer coaches have all the vacuum spaghetti under the dash and the head aches that go along with it. I don't know when the change took place but I think it was '83 or '84.
"Socialist governments traditionally do make a financial mess. They always run out of other people's money. It's quite a characteristic of them."
